How do you work out 8x plus 6 equals 2x plus 24?
8x + 6 = 2x + 24 To solve, collect like terms on each side; collect the x's on the left, the numbers on the right: 8X + 6 = 2x + 24 8x - 2x = 24 - 6 6x = 18 6x / 6 = 18 / 6 x = 3
How do you solve 8x plus 6 equals 3x-4?
8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2
What is -8x plus 3 equals 251?
If -8x+3=251, then 8x=-248. Therefore, x=-31.
8x plus 30 equals 4x plus 18 solve for x?
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
What are the solutions for the quadratic equation x2 plus 6x equals 16?
x2 + 6x = 16=> x2 + 6x - 16 = 0=> x2 + 8x -2x - 16 = 0=> (x+8)(x-2) = 0=> x = -8 or x = 2So, the solutions of the quadratic equation x2 + 6x = 16 are -8 and 2.
Solve x 6x - 7 equals 8x plus 9?
x= -8
How do you solve for 6x-20 equals 8x?
6x-20 = 8x 6x-8x = 20 -2x = 20 x = -10
How do you solve x2 plus 6x equals -9?
2x+6x=-9 => 8x=-9=> x=-8/9
Solve 8x plus 39 equals 2x-15?
8x+39 = 2x-15 6x = -54 x = -9
6x equals 8x plus 28?
6x = 8x+28 6x-8x = 28 -2x = 28 x = -14
Solve for x 8x equals 2x plus 15?
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
What is 6x plus 3 equals 8x plus 14?
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
How do you get the answer 8x plus 11 equals 33 plus 6x?
8x + 11 = 33 + 6x 8x - 6x = 33 - 11 2x = 22 x = 11
How do you solve 9 plus 6x equals 25-2x?
9+6x = 25-2x 6x+2x = 25-9 8x = 16 x = 2
How do you solve -8x equals 14 equals -6x -30?
I'm an orange!
What is 8x-17 equals 6x plus 11?
8x-17=6x+112x=28x=14
Solve 8x equals 2x plus 6?
To solve this equation, we will first subtract 2x from each side:8x=2x+6 (8x minus 2x=6x)6x=6Now, to isolate x, we must divide out the 6:6x=6 (6x divided by 6= x)x=1If 8x=2x+6, x=1
