Answer
The solution is -3
Work Step by Step
10x+15 =6x+3 Subtact 15 from both sides 7
10x+15 -15 =6x+3 -15 Simplify
10x =6x - 12 Subtract 6x from both sides
10x -6x =6x - 12 -6x Simplify
4x = -12 Divide both sides by 4
$\frac{4x}{4}$ = $\frac{-12}{4}$
x = -3
The solution is -3
Check
10x+15 =6x+3
10(-3)+15 =6(-3)+3 Multiply
-30 +15= -18 +3
-15=-15
