Select all the equations that have {7} as its solution set 65 - 20 = 6.2 + 9

22 +1 = 8x - 5

9- 2 = 14

3+ 40 = 52 - 4

2 5/8 is the final answer! : )

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
