Question

1) 4x - 7 = 2x - 8
2) 6m - 4 = 12 - 9m
3) m + 4 - 3m = 4 + 12m
4) 3 + 4m - 9 = 6m - 4 + 12
5) -5 + 3x + 4 = 11 + 9x
6) 3(x + 2) = 15
7) -2 (-m + 2) = 3(2m + 1 )
8) 12m + 3(m - 1 ) = -2(m + 1 ) + 16



????????????????????????????​

Answer 1

1) 4x-2x = -8 +7

2x = -1

x = -1/2

2) 6m +9m = 12 +4

15m = 16

m = 16/15

3) -2m - 12m= 4 -4

- 14m = 0

m = 0/-14

m = 0

4) 4m-6m = +8 +6

- 2m = 14

m = 14/-2

m = -7

5) 3x - 9x = 11 +5 -4

- 6x = 16 -4

- 6x = 12

x = 12/-6

x = - 2

6) 3x + 6 = 15

3x = 15 -6

3x = 9

x = 9/3

x = 3

7) +2m - 4 =6m +3

2m -6m = 3 +4

- 4m = 7

m = - 7/4

8) 12m +3m -3 = - 2m -2 +16

15m -3 = -2m +14

15m +2m = 14 +3

17m = 17

m = 17/17

m = 1
