Question

Which of the following values for x and y make the equation 4x + 2y + 3 = 19 true?

x = 5, y = 3
x = 4, y = 5
x = 3, y = 2
x = 2, y = 5

Answer 1

Answer: the answer is c

Step-by-step explanation: Hope this helped!!

Answer 2

To answer the question above, substitute the values of x from each choice then solve for y. This is shown below.

A. x = 5, 4(5) + 2y + 3 = 19 , y = -7

B. x = 4, 4(4) + 2y + 3 = 19 , y = 0

C. x = 3, 4(3) + 2y + 3 = 19 , y = 2

D. x = 2, 4(2) + 2y + 3 = 19 , y = 4

From the calculations above, only the third choice has a similar value of y to the value in calculations.

Thus, the answer is letter C.
