Step-by-step explanation:
Let's solve your equation step-by-step.
4x+2(x−3)=3x+x−12
Step 1: Simplify both sides of the equation.
4x+2(x−3)=3x+x−12
4x+(2)(x)+(2)(−3)=3x+x+−12(Distribute)
4x+2x+−6=3x+x+−12
(4x+2x)+(−6)=(3x+x)+(−12)(Combine Like Terms)
6x+−6=4x+−12
6x−6=4x−12
Step 2: Subtract 4x from both sides.
6x−6−4x=4x−12−4x
2x−6=−12
Step 3: Add 6 to both sides.
2x−6+6=−12+6
2x=−6
Step 4: Divide both sides by 2.
2x
