Let's solve your equation step-by-step.
(Layout equation)
5x−2+x+12=40
Step 1: Simplify both sides of the equation.
5x−2+x+12=40
5x+−2+x+12=40
(5x+x)+(−2+12)=40(Combine Like Terms)
6x+10=40
6x+10=40
Step 2: Subtract 10 from both sides.
6x+10−10=40−10
6x=30
Step 3: Divide both sides by 6.
6x/6=30/6
Step 4: Answer
x=5
So the answer is x=5.
