Question

Exercise 15A
Solve the following equations.
1. 3(x + 1) + 4x = 24​

Answer 1

Step-by-step explanation:

3(x+1) +4x = 24

3x + 3 + 4x = 24

7x + 3 = 24

7x = 24-3

7x = 21

x = 3

Answer 2

1.3 (x+1)+4x=24

1.3x+1.3+4x=24

5.3x+1.3=24

5.3x=24-1.3

x=22.7/5.3

x=227×10/53×10

x=227/53

x=4.28
