Question

en, check the solution.
= -3
n + 8 - = -3 -
th sides.
each side. n + 0 =
n =
n:
n + 8 = -3
for n. + 8 ? -3
= true

1. 24 = t + 6

subtract from both sides. 24 - = t + 6 -
simplify each side. = t +
= t
solution:
check. 24 = t + 6
substitute for t. 24 ? + 6
= true
check the solution.
6
9+ = (
-11
= -15

• 8

1. r + 2 = 10
2. 7 = s + 4
3. -10 = y + 5
4. 7 + b = 3
5. x + 6 = -10
6. 6 + n = 18
7. 3 = z + 7
8. c + 12 = 4
9. 5 + a = -20
10. y + 8 = 3

a partner how you solve the equation in number 8
e.
equation y = 10. then, write a new equation by adding
ess than 10 to the left side of the equation. ask a
solve the new equation. check the solution.

Explanation:

Step1: Isolate $y$ by subtracting 5

$ -10 - 5 = y + 5 - 5 $

Step2: Simplify both sides

$ -15 = y $

Step3: Check by substituting $y=-15$

$ -10 = -15 + 5 $
$ -10 = -10 \quad \text{true} $

Answer:

$y = -15$
