Question

2 Solve each of the following by trial and
error method.
(1) 3+x=8
(2) 2a - 7 = 3
(3) 5y = 30
(4) 3x - 7=x+5
(v) = 2x/3=4
(vi) 3 - 6 = 2t-4

pls solve it with method i will make him/she a brainlist​

Answer 1

Step-by-step explanation:

(1)3+x=8

x=8-3=5

(2) 2a-7=3

2a=3+7

2a=10

a=10/2=5

(3)5y=30

y=30/5=6

(4)3x-7=x+5

3x-x=5+7

2x=12

x=12/2=6

(v)=2x/3=4

2x=4×3

2x=12

x=12/2=6

(vi)3-6=2t-4

-3=2t-4

-3+4=2t

1=2t

1/2=t

t= 0.5

hope you understand
