Question

Solve the equation 7x-3(x-6)=30

Answer 1

x=3

Explanation:

Step 1: Simplify both sides of the equation.

7x−3(x−6)=30

7x+(−3)(x)+(−3)(−6)=30(Distribute)

7x+−3x+18=30

(7x+−3x)+(18)=30(Combine Like Terms)

4x+18=30

4x+18=30

Step 2: Subtract 18 from both sides.

4x+18−18=30−18

4x=12

Step 3: Divide both sides by 4.

4 divided by 12 =3

4 divided 4 = 1

x=3

Answer 2

The answer is x = 3

Explanation:

7x - 3(x-6) =30

7x -3x+18=30

4x= 30-18

4x=12

x=12/4

x=3
