Question

Solve the following by the systematic method and verify your answers a) x + 7 = 10 b) 3x + 2 = 8 c) 5x-9=1 d) 7(x - 1)=20 e) 6x=54 f) x-4/2=1 ​​

Answer 1

Answer:

a) 3 b) 2 c)2 d)27/7 e) 9 f) 6

Step-by-step explanation:

a) x + 7 = 10

x = 10 - 7

x = 3

b) 3x + 2 = 8

3x = 8 - 2

x = 6/3

x = 2

c) 5x - 9 = 1

5x = 9+1

x = 10/5

x = 2

d) 7(x-1) = 20

7x-7 = 20

7x = 20 + 7

7x = 27

x = 27/7

e) 6x = 54

x = 54/6

x = 9

f) x - 4 /2 = 1

x - 4 = 1 × 2

x - 4 = 2

x = 4 + 2

x = 6
