Question

H) 8x-32=(-20x):4+46
i ) 4x-8x-4.9=-x-3x-12.3
J ) -5x-15+x+3=-8+6x-14
K) -15x+8x-36=-21:3+5x-15
M) 8x-(-15+3-17)+18=2x-(-5)
N) 18x-(-10)+(-68)=13x-(-25+8)​

Answer 1

H ) 8x - 32 = - 20x / 4 + 46

8x + 20x / 4 = 46 + 32

8x + 5x = 78

13x = 78

x = 78 / 13

x = 6

I ) 4x - 8x - 36 = - x - 3x - 36

4x - 8x + x + 3x = - 36 + 36

0 = 0

J ) - 5x - 15 + x + 3 = - 8 + 6x - 14

- 5x + x - 6x = - 8 - 14 + 15 - 3

- 10x = - 10

x = - 10 / - 10

x = 1

K ) - 15x + 8x - 36 = - 21 / 3 + 5x - 15

- 15x + 8x - 5x = - 21 / 3 - 15 + 36

- 12x = - 7 - 15 + 36

- 12x = 14

x = 14 / - 12

x = - 1.16666

M )8x + 15 - 3 - 17 + 18 = 2x + 5

8x - 2x = 5 - 15 + 3 + 17 - 18

6x = - 8

x = - 8 / 6

x = - 1.33333

N ) 18x + 10 - 68 = 13x + 25 - 8

18x - 13x = 25 - 8 - 10 + 68

5x = 75

x = 75 / 5

x = 15
