Question

5.
Solve the following equations.
(b) 2 (x – 5) = 10
(a) 4x - 3 = 2x + 1​

Answer 1

Answer:

2(x-5) =10

2x -10 =10

2x =10 +10

2x = 20

x= 20/2

x =10

4x -3 =2x+1

4x -2x -3 =1

2x = 1+3

2x =4

x = 2

Answer 2

Answer:

(a) x = 2

(b) x = 20

Step-by-step explanation:

(a) 4x - 3 = 2x + 1

4x - 2x = 3 + 1

2x = 4

x = 4/2

x = 2

(b) 2 (x - 5) = 10

2x - 10 = 10

2x = 10 + 10

2x = 20

x = 20/2

x = 10
