Question

is x = 8 a solution to the equation x + 7 = 15
A yes, because 8+7 is not true.
B yes, because 8+7 = 15 is true
C no, because 8+7=15 is true
D no, because 8+7=15 is not true

Answer 1

Answer:

B.

Step-by-step explanation:

x + 7 = 15

x = 15 - 7

x = 8

we know that only 8 + 7 gives 15 in this particular equation

Answer 2

Question:-

is x = 8 a solution to the equation x + 7 = 15

A yes, because 8+7 is not true.

B yes, because 8+7 = 15 is true

C no, because 8+7=15 is true

D no, because 8+7=15 is not true

Answer:-

option B yes, because 8+7 = 15 is true

Explanation:-

=> x + 7 = 15

=> x = 15-7

=> x = 8

-------------------------------------------------------

We know that 8+7 equals to 15.

Therefore , x = 8 is the solution of the equation x+7 = 15
