Question

Solve the following equations.
(a) 2y+33=100 (b) 162 = 80
(c) 7X-9-2x =26​

Answer 1

• 2y + 33 = 100

2y = 100 - 33

2y = 67

y = 67/2

• 162 = 80

= 162 / 80

= 81 / 40

• 7x - 9 - 2x = 26

7x - 2x - 9 = 26

5 - 9 = 26

4 = 26

= 26 / 4

= 13 / 2

Answer 2

Answer:

a) 2y=100-33

2y=67

y=67÷2=33.5

b)162=80

81=40

c) 7X-9-2x=26

5x-9=26

5x=26+9

5x=35

x=35÷5

x=7
