Exercise 2 Page 441

y=-16

Practice makes perfect

To solve the equation, we have to isolate y on one side. Using the Subtraction Property of Equality, we can subtract 5 from both sides of the equation. This will eliminate addition on the left-hand side and isolate y.

y+5=-11

LHS- 5=RHS- 5

y+5- 5=-11- 5

Subtract terms

y=-16

To check that this solution is correct, let's substitute y=-16 into the original equation and simplify.

y+5=-11

y= -16

-16+5? =-11

Add terms

-11=-11 ✓

Because the left-hand side and right-hand side are equal, y=-16 is the correct solution.
