Question

which equations have 8 as a solution?
14 - v = 6 v + 7 = 15 2v = 15 64 ÷ v = 8
select all the equations that have 8 as a solution.
a. v + 7 = 15
b. 2v = 15
c. 64 ÷ v = 8
d. 14 - v = 6

Explanation:

Step1: Check Equation A ($v + 7 = 15$)

Substitute $v = 8$: $8 + 7 = 15$ → $15 = 15$ (True).

Step2: Check Equation B ($2v = 15$)

Substitute $v = 8$: $2×8 = 16 ≠ 15$ (False).

Step3: Check Equation C ($64 ÷ v = 8$)

Substitute $v = 8$: $64 ÷ 8 = 8$ → $8 = 8$ (True).

Step4: Check Equation D ($14 - v = 6$)

Substitute $v = 8$: $14 - 8 = 6$ → $6 = 6$ (True).

Answer:

A. $v + 7 = 15$, C. $64 ÷ v = 8$, D. $14 - v = 6$
