Question

i) 7 x + 2 + 3x = 46 ii) -2x + 5x = 18 iii) -8x - 6x - 4 - 3 = 28​

Answer 1

Step-by-step explanation:

1) 10x +2 = 46

10x = 46-2

10x = 44

X= 44/10 = 4.4

2) 3x= 18

X= 18/3

X = 6

3) -14x -7 = 28

-14x = 28-7

-14x = 21

X= 21/-14

X = -3/7

Answer 2

Step-by-step explanation:

1) 7 x + 2 + 3x = 46

10x =46-2

x = 44/10

2) -2x + 5x = 18

3x = 18

x = 6

3)-8x - 6x - 4 - 3 = 28

- 14x - 7 = 28

- 14x = 28+7

- 14x = 35

x = - 35/14

x = - 7/2
