What is the solution to the equation 4x + 2(x − 3) = 3x + x − 12?
−3
−1
1
3

Answer 1

-3

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

2

x=−3

Answer 2

-3

steps:

4x+2x+6=4x-12

6x-6=4x-12

2x=-6

x=-3
