first and last are your answers

x + 1 = 7
6+ 1 = 7
7 = 7 (true)

6(x+2)=2x-5(x-8)+26
6(6+2) = 2(6) - 5(6-8) +26
6(8) = 12 - 5(-2) + 26
48 = 12 + 10 + 26
48 = 48 (true)

5)
first and last are your answers

3(2/5)+4=5 1/5
6/5 +4=26/5
6/5 20/5 = 26/5
26/5 = 26/5 (true)

1/3 (2/5) + 5/3 = 2(2/5)+1
2/15 + 5/3 = 4 /5 + 1
2/15 + 25/15 = 12/15 + 15/15
27/15 = 27/15 (true)

Number 1 is a because you would minus 1 from both sides to get the x alone.
