Question

Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4 by substituting x = 1 and x = 2.

Answer 1

44

Explanation:

So if we do 4(x+x+7)-2x+8-4 X=1

then 4(1+1+7) -2(1) +8-4

and 4(9)+2

it would be 38

then if we do 4(x+x+7)-2x+8-4 X=2

and 4(2+2+7) -2(2)+4

also 4(11)-4+4 it would be 44

Answer 2

4(x+x+7)-2x+8-4 X=1
4(1+1+7) -2(1) +8-4
4(9)+2
38

4(x+x+7)-2x+8-4 X=2
4(2+2+7) -2(2)+4
4(11)-4+4
44
