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.
