Question 343281
4x+7=8x-5

Since 8x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 8x from both sides.
4x+7-8x=-5

Since 4x and -8x are like terms, add -8x to 4x to get -4x.
-4x+7=-5

Since 7 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 7 from both sides.
-4x=-7-5

Subtract 5 from -7 to get -12.
-4x=-12

Divide each term in the equation by -4.
-(4x)/(-4)=-(12)/(-4)

Simplify the left-hand side of the equation by canceling the common factors.
x=-(12)/(-4)

Simplify the right-hand side of the equation by simplifying each term.
x=3
