Answer
The solution is -5
Work Step by Step
7x-1=8x+4 Add 1 to both sides of the equation
7x-1 + 1=7=8x+4 +1 Simplify
7x =8x + 5 Subtract 8x from both sides
7x -8x =8x + 5 -8x Simplify
-x = 5Divide both sides by -1
$\frac{-x}{-1}$ = $\frac{5}{-1}$
x = -5
The solution is -5
Check
7x-1=8x+4
7(-5) -1 =8(-5)+4 Multiply
-35-1= -40 +4
-36=-36
