a)
5x - 2x + 7 = x + 1 \\ 3x + 7 = x  + 1  \\ 3x - x = 1 - 7 \\ 2x =  - 6 \\ x =  - 3
b)
x + x + 2 = x + 4 + 31 \\ 2x + 2 = x + 35 \\ 2x - x = 35 - 2 \\ x = 33
C)
2(m + 7) = 3(m - 10) \\ 2m + 14 = 3m - 30 \\ 14 + 30 = 3m  - 2m \\ m = 34
d)
x - 3 \div 5 + 3 = 7x - 1 \div 3 \\ x - 3   + 35 \div 5 = 7x - 1 \div 3 \\ x - 32 \div 5 = 7x - 1 \div 3 \\ 35x - 5 = 3x - 96 \\ 35x - 3x =  - 96 + 5  \\ 32x =  - 91 \\ x =  - 91 \div 32
