Question

Determine which integer in the solution set will make the equation true. t − 42 = −14 S: {−56, −28, 3, 28}

Answer 1

28

Explanation:

Determine which integer in the solution set will make the equation true. t − 42 = −14 {−56, −28, 3, 28}

replace 28 for t:

t − 42 = −14

28 − 42 = −14

−14 = −14

Answer 2

28

Explanation:

You want the value of t that satisfies t − 42 = −14.

One-step linear equation

The solution to this 1-step linear equation is to add the opposite of the unwanted constant (-42).

Adding 42 to both sides of the equation gives ...

t -42 +42 = -14 +42

t = 28

The integer that makes the equation true is 28.
