Question

A. & b. Plz answer with solution........ ​

Answer 1

Step-by-step explanation:

a. 2x+12=20

subtracting 12 from both sides

2x+12-12=20-12

2x+0=8

2x=8

diving both sides by 2

x=2

b.3y-4=16

adding 4 to both sides

3y-4+4=16+4

3y+0= 20

3y=20

dividing both sides by 3

y = 6.66

Answer 2

Answer:

2x + 12 = 20

Step-by-step explanation:

= 2x=20-12

= 2x=8

= x=8/2

= x=4.

b.3y-4=16

= 3y=16+4

= 3y=20

=. y=20/3

= y=6.6
