Question

Looking at Yari's equation below, what

do you notice about both sides of the
equation?
2(x + 10) - 17=5+2x-2
2x+ 20 - 17=3+2x
2x+3 = 3 + 2x

A)Only the constants are the same on both sides.

B) Both sides are exactly the same.

C) The variable terms on each side of the equation are different.

D) Only the variable terms are the same on both sides.

Answer 1

While comparing both sides of the equation Both sides are exactly the same.

Option: B.

Explanation:

We are given with a equation and its steps in the question.

At the last step Yari found that equations on the both side are equal.

Let us check the equation one by one to find the similarities.

1) 2(x + 10) - 17=5+2x-2.

2(x)+2(10)-17=2x+5-2.

2x+20-17 = 2x+3.

2x+3=2x+3.

Both sides are equal in this equation.
