Question

(ii) 2y = 1
(iv) 2x - 3 = 13
(v) 12y -
Verify by substitution that
(i) the root of 3x - 5 = 7 is x = 4
(iii) the root of 5x - 8 = 2x - 2 is x =
(v) the root of = 8 is z = 56
Solve each of the following equations
(i) y + 9 = 13 (i) x - 7 = 10​

Answer 1

Answer:

ii) y = 1/2

iv)

$2x - 3 = 13 \\ 2x = 13 + 3 \\ 2x = 16 \\ x = \frac{16}{2} \\ x = 8$

v) question is not given correctly

Answer 2

Answer:

1 2y=1

y=1-2

y=1

2 2x-3=13

2x=13+3

2x=16

x=16÷2

x=8

I know this much only

hope it's helps you✌
