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

(a) 3l = 42

(b) b/2= 6

(c) p/7=4

(d) 4x =25

(e) 8y=36

(f) z/3=5/4

(g) a/5=7/15

(h) 20t=-10

(a) 3l = 42

(b) b/2= 6

(c) p/7=4

(d) 4x =25

(e) 8y=36

(f) z/3=5/4

(g) a/5=7/15

(h) 20t=-10

(a) 3I =42

Or, I=42/3 = 14

(b) b/2 = 6

Or, b=6×2=12

(c) p/7 = 4

Or, p= 4×7 = 28

(d) 4x=25

Or, x=25/4

(e) 8y=36

Or, y= 36 /8 = 36 ÷4/8÷4 = 9/2

(f) z/3= 5/4

Or, z= (5/4) ×3 =15/4

(g) a/5=7/15

Or, a= (7/15)× 5 =7/3

(h) 20t = -10

Or, t = -10 /20 = -1/2
