Question

Using substitution, which number from the set (15,25,35,55) make the equation y + 15=40 true (1 point)

25

55

35

15

Answer 1

To determine which number from the set makes the equation y + 15 = 40 true, we can substitute each number from the set one by one and check if it satisfies the equation.

Substituting 25 into the equation:
25 + 15 = 40
40 = 40

Since 25 satisfies the equation, the answer is 25.
