Question

2 Give first the step you will use to separate the variable and then solve the equation:

(a) 2x=12
(b) 4y=3
(c) 5y=10
(d) 10m=200
(e) x/7=12
(f) 5m/2=11
(g) n/6=0
(h) x/4=3/5
​

Answer 1

Answer:

a. 2x =12

x = 12 / 2

x = 6

b. 4y =3

y = 3 /4

c. 5y =10

y = 10 /5

y = 2

d. 10m =200

m =200/10

m = 20

e. x/7=12

x = 12 × 7

x = 84

f. 5m/2=11

5m = 11×2

5m = 22

m = 22/5

g. n/6=0

n =0×6

n = 0

h. x/4= 3/5

x = 3/5×4

x = 3×4 / 5

x=12/5
