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✓
