Question

Solve the following equations.
(b) 5(x - 5) = 30
=
(d) 5x - 15 = 2x + 6

(c) 16 - x/2 =10


​

Answer 1

Step-by-step explanation:

b) x-5=6

or x= 6+5

or x=11

d) 3x=21

or x=7

c) -x/2= -6

or x=32

Answer 2

Answer:

(b) 5(x - 5) = 30

5x - 25 = 30

5x = 30 + 25

5x = 55

x = 55/5

x = 11

(c) 16 - x/2 = 10

16 - 10 = x/2

6 = x/2

x = 6 × 2

x = 12

(d) 5x - 15 = 2x + 6

5x - 2x = 15 + 6

3x = 21

x = 21/3

x = 7
