Answer 1

1. 5x+2=22

5x = 22 -2

5x = 20

x = 4

2. 2x =12-5

2x= 7

x = 3.5

Verification of 1st sum

5×4 +2 =22

20+ 2 =22

22=22

Verification of 2nd sum

2×3.5 +5 = 12

7 +5 =12

12=12

Hope u understood

Answer 2

Answer:

This is your answer mate

Step-by-step explanation:

5x+2=22

5x=22-2

5x=20

x=20/5

x=4

2) 2x+5=12

2x=12-5

2x=7

x=7/2

3) a/5+3=8

a/5=8-3

a/5=5

a=5×5

a=25

4)3b/7-1=5

3b/7=5+1

3b/7=6

3b=6×7

b=42/3

b=14
