Question

Solve each of the following equations :
(1) y + 9 = 13
(2) x - 7 = 20
(3) 4x = 28
(4) 3y = 36
(5) 11 + X = 19
(6) X/3 = 4
(7) 2x - 3 = 9
(8) 1/2 x 7 = 11
(9) 2y + 4 = 3y
(10) z - 3 = 2z - 5

( please answer as soon as possible -.- )​

Answer 1

Answer:

1 ) y=4

2 ) x=27

3 ) x=7

4 ) y=12

5 ) x=8

6 ) x=12

7 ) x=6

9 ) y=4

10) z=2

Answer 2

Step-by-step explanation:

(1) y=13-9=4

(2) x=20+7 =27

(3) x=28/4=7

(4) y=36/3=12

(5) x=19-11=8

(6) x=4×3=12

(7) 2x=9+3

2x=12

x=12/2=6

(8) 3.5

(9) 2y-3y=-4

-1y=-4

y=-4/-1

y= 4

(10) z-2z=-5+3

-1z=-2

z=-2/-1

z=2
