Question

Steps for solving 6x - 18 = 54 are shown.
Explain how Step 1 helps solve the equation.

Answer 1

`\huge \boxed{X=12}`

Explanation:

Add by 18 from both sides of equation.

`\displaystyle 6x-18+18=54+18`

Add numbers from left to right.

`\displaystyle 54+18=72`

`\displaystyle 6x=72`

Divide by 6 from both sides of equation.

`\displaystyle (6x)/(6)=(72)/(6)`

Simplify, to find the answer.

`\displaystyle 72/6=12`

`\huge \boxed{x=12}`, which is our answer.

Answer 2

x = 12

Step 1 helps solve the equation, for it helps isolate the x, which is what you are solving for.

Explanation:

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS:

Step 1: Add 18 to both sides.

6x - 18 (+18) = 54 (+18)

6x = 54 + 18

6x = 72

Step 2: Divide 6 from both sides:

(6x)/6 = (72)/6

x = 72/6

x = 12

x = 12 is your answer.
