To solve for ( x ) in the equation ( 5x - 18 = 4x + 7 ), first, isolate ( x ) on one side. Subtract ( 4x ) from both sides:
( 5x - 4x - 18 = 7 ) simplifies to ( x - 18 = 7 ).
Next, add 18 to both sides to get ( x = 25 ). Thus, the value of ( x ) is 25.
If you mean: 4x-14x+7 then the expression can be simplified to 7-10x
If you mean 49+6 = 4x-7 then the value of x is 15.5
4x + 3, where x = 7 4(7) + 3 = 28 + 3 = 31

Let the unknown number be x: 4x-7 = 13 Moving -7 to the other side of the equation changes it to +7: 4x = 13+7 4x = 20 Divide both sides of the equation by 4 to find the value of x: x = 5
this is what you would: 4x+6=3x-1 -6 -6 ---- 4x=3x-7 -3x -3x ---- 1x=-7 ---- x=-7
what is the product of ( 4x-7) (4x+7)
If you mean: 3x -7 +4x = 28 then the value of x works out as 5
First arrange this simultaneous equation in the form of: 4x+5y = 33 4x-2y = -2 Subtract the bottom equation from the top equation remembering that a - - is equal to a +: 7y = 35 Divide both sides by 7 to find the value of y: y = 5 Substitute the value of y into the original equations to find the value of x: So: x = 2 and y = 5

To find the degree of the polynomial (x^6 + 3 - 2x^2 + 4x^7 - 4x), we look for the term with the highest power of (x). The terms are (x^6), (-2x^2), (4x^7), and (-4x). The term (4x^7) has the highest degree, which is 7. Therefore, the degree of the polynomial is 7.
If: 4x-6 = 54 then the value of x works out as 15
