Question

A ) 11x +7 = -6
B ) 3x +1 = 19
C ) 5 + 2x = 1
D ) 5x +3 = 7
E ) x - 3 = 1
F ) 2x -3 = 17

Answer 1

A) 11x + 7 = - 6

11x = - 6 - 7

11x = - 13

x = - 13/11

B) 3x + 1 = 19

3x = 19 - 1

3x = 18

x = 18/3

x = 6

C) 5 + 2x = 1

2x = 1 - 5

2x = - 4

x = - 4/2

x = - 2

D) 5x + 3 = 7

5x = 7 - 3

5x = 4

x = 4/5

E) x - 3 = 1

x = 1 + 3

x = 4

F) 2x - 3 = 17

2x = 17 + 3

2x = 20

x = 20/2

x = 10
