Answer 1

Answer:

Option a and option c will be the answer .

6-x+2x-7+2x = 3x-1

a) x+x+6-7+x=3x-1

b) 2x+2+x=3x+2

c) 3 – x + 2x – 4 + 2x= 3x-1

D. x – 1

E. x + 1

so option a and c match.

Answer 2

Answer:

Answers are A and C.

Step-by-step explanation:

First of all, see 6 +(–x) + 2x + (–7) + 2x = 6-x+2x-7+2x = 3x-1....(1)

So, the answers are those which satisfy the above equation.

See in option A, its x + x + 6 – 7 + x.

Solving it,

2x +6-7+x = 3x-1. So, it satisfies the equation (1). So, option A is an answer.

Now, see in option C, its 3 – x + 2x – 4 + 2x.

Solving it,

3+x-4+2x = -1+3x = 3x-1. So, it also satisfies the equation (1).

So, option C is another answer.
