Answer: y=6
Step-by-step explanation:
Let's solve your equation step-by-step.
30y+40=220
Step 1: Subtract 40 from both sides.
30y+40−40=220−40
30y=180
Step 2: Divide both sides by 30.
30y/30= 180/30
y=6
Given:
The expression is

To find:
The value of the given expression when y=-5.
Solution:
We have,

Putting y=-5, we get




Therefore, the value of the given expression is 50 when y=-5.
