Question

18x+30=6(2x-1). What is a first step to isolate the variable there can be more than one answer A. Subtract 30 from 18x +30 B. Divide both sides by 6 C. Multiple both sides by 6 D. Multiple 2x-1 by 6

Answer 1

D

Explanation:

18x+30=6(2x-1)

My first step would be to distribute the 6 so that the next step you can subtract 30 from both sides.

Answer 2

Divide both sides by 6

or

Multiply 2x-1 by 6

Explanation:

18x+30=6(2x-1).

Divide both sides by 6

18x/6+30/6=6/6(2x-1).

3x +5 = 2x-1 or

We could multiply 2x-1 by 6

18x+30 = 6(2x-1)

18x+30 = 12x-6
