Winston is solving the equation 5x - 3 (10 - 2x) = 9 (2x + 6).

The following shows the steps he has used so far to solve the equation

Step 1: 5x - 3 (10) - 3 (-2x) = 9 (2x) + 9 (6)

Step 2: 5x - 30 + 6x = 18x + 54

Which statement describes a possible next step that Winston can use to solve this equation?

Question options:

a] Subtract 30 from both sides of the equation.

b] Add 6x to both sides of the equation.

c]Add 18x to both sides of the equation.

d] Subtract 5x from both sides of the equation.

This is the concept of algebra, in explaining the steps we use we proceed as follows;

5x-3 (10-2x) = 9 (2x+6)

step1:

5x-3 (10) - 3 (-2x) = 9 (2x) + 9 (6)

step2:

5x-30+6x=18x+54

next we want to put like terms together, begin by subtracting 5x from both sides:

The answer is D] Subtract 5x from both sides of the equation.
