Question

What value of y makes the equation true?

3 ( 2y - 5 ) + 15 = 12

y =

Answer 1

3 (2y-5) + 15 =12
6y-15+15=12
6y=12
y=2

Answer 2

To find value of y:-

________________________________

Step 1:

3 ( 2y - 5 ) + 15 = 12

Right the equation

________________________________

Step 2:

6y-15+15=12

open the brackets and multiply 3 with 2y - 5

________________________________

Step 3:

6y=12

Subtract 15 with 15 to get 0

________________________________

Step 4:

y=12÷6

divide 12 with 6 to get value for y

________________________________

Step 5:

y=2

Value of y comes 2

________________________________

Confermimng :

3(2×2-5)+15=12

3(4-5)+15=12

3(-1)+15=12

-3+15=12

12=12

hence proved

⚡Final answer:

Y=2✓

We have to keep value of y as 2 to make the equation true✓
