Question

Which would not be a step in solving 18=2(4+x)?

A) Use the distributive property.
B) Collect variables terms on one side.
C) Collect like terms.
D) Isolate the variable.

Answer 1

B because there is only one variable in the equation.

Answer 2

B) Collect variables terms on one side.

Explanation:

Here, the given equation is,

`18=2(4+x)`

By Distributive property in right side,

`18=8+2x`

Subtracting 8 on both sides, ( Isolating variable x )

`18-8 = 8 + 2x-8`

Collect like terms,

`10=2x`

Dividing both sides by 2 ( Isolating variable x )

`5 = x`

Which is the solution of the given equation,

Hence, by the above explanation it is clear that we used all options except option B.

⇒ Option B would not be a step in solving 18=2(4+x).
