Question

1) 3×+5=17
2) 5×-40=2-×
3) 11×-3×-8=5(×-2)+3×
4) 4 (2×-1)=7(16×-8)
5) 7 (2q-1)-3(2-q)+ 5(q+4)=7
6) 4 (2m-1)-3m= 2 (4m-1) - (2-m)

Answer 1

1 ) 3× = 17 - 5
    3× = 12
      x = 12 /3
x = 4

2)5x + x = 2 + 40
    6x = 42
     x = 42/6
    x= 7

3)8x -8 = 5x - 10 + 3x
 8x - 8 = 8x - 10
 8x - 8x = - 10 + 8
  18

4)8x - 4 = 112x - 56
    8x - 112x = - 56 + 4
      104x = 52
       x = 52/104
      x = 1/2
5) 14q - 7 -6 + 3q + 5q + 20 = 7
    22q +7 = 7
    22q = 0
      q = 0
6)8m - 4  - 3m = 8m - 2 -2 +m
   5m - 4 = 7m -4
   -4 + 4 = 7m - 5m
   0 = 2m
m = 0
