2(2n + 5) = 12
2n + 5 = 6
2n = 1
n = 1/2
2nd [CATALOG], solve( , enter equation, variable and guess after the bracket, close brackets with " ) ". You can also put lower and upper bounds after the guess.
You can write this as two equations, and solve them separately. The two equations are:x - 19 = -3and:-x - 19 = -3
5x+3 = x+4 5x-x = 4-3 4x = 1 x = 1/4 Thats not even close to how you solve it. First of all the equation is written 5^(x+3)=x+4. Simple Logarithms are needed to solve.
Yes, it won't be exact, but you can round the number to get a close estimate.
60(x - 15) = 2500 (then simplify the left side of the equation) 60x - 900 = 2500 (then add 900 from both sides of the equation) 60x = 3400 (thn divide both sides by 60 to solve for x) x = 56.66666 (56-2/3)
means it is 6(1.042)=t+7. so in this equation we have to find the value of t. we just take '7' in opposite side of equal to side. so that t=6*1.042-7 because we know in general that if there is no sign then there is a multiplication.
Unfortunately, limitations of the browser used by WA means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. While you HAVE tried to do so, the end of the question is missing some symbols. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc.
You cannot solve a variable. You can solve an equation to find the value (or range of values) of a variable. How you do that depends on the nature of the equation that you have. Linear and quadratic equations are relatively simple, as are many trigonometric and exponential equations. But some cannot be solved in such a way and a numerical solution is required. Here you would make a guess and then improve on that guess and then improve on that until you were satisfied that you were close enough to the real answer.
6(x + 7) = 6x + 42
Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether "x plus y squared" means x + y^2 or (x + y)^2. You will need to use a code, for example b1 (open bracket) and b2 (close bracket), because the browser will reject brackets!Here, it is not clear whether you mean 2^a + 3 or 2^(a+3)
6/2(1+2)=? The answer is 9. The BIDMAS or PEMDAS Rule says that brackets must be done first. 1) (1+2)=3 Then you do multiplication or division first since it is the next step in the rules that apply to this equation. Many are confused as to which one they are supposed to do because they give a different answer. However, all equations are solved by left-to-right if you must choose from times and divide, or plus and minus. 2)6/2=3 Now the equation is: 3(3) This means multiply. 3)3*3=9 The equation is solved.
2(2*4-5)+6 = 12
