Q1: Fill in the blanks:-
(i) Solution of equation 2x = 4 is, x =
(ii) Solution of equation
3 is, x =
(iii) Solution of equation 3x + 2 = 8 is, X =
(iv) Solution of equation 5 y = 2y +15 is, y​

Answer 1

Step-by-step explanation:

(i)2x=4

x=4/2

x=2

(iii) 3x+2=8

3x=8-2

3x=6

x=2

(iv)5y=2y+15

5y-2y=15

3y=15

y=15/3

y=5

Answer 2

(i)x= 2

(ii) x=3,

(iii)x= 2

(iv)y= 5
