Steps for solving 3x+18=54 are shown explain how step 1 solve the equation.

Option C is correct

Subtracting 18 from both sides isolates the variable term

Step-by-step explanation:

Given an equation:

Subtract 18 from both sides we get;

Step 1.

Simplify:

Step 2.

Divide both sides by 3 we have;

Step 3.

Simplify:

Step 4.

x = 12

Therefore, Subtracting 18 from both sides isolates the variable term in step 1 helps to solve the equation.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.
