Question

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

Ox=5₁y=3
Ox=4,y=5
Ox=3,y=2
Ox=2,y=5

Answer 1

x = 3, y = 2

Explanation:

Substitute the values of x from each alternative in the previous question, then solve for y. This is depicted below.

• A. y = -7, x = 5, 4(5) + 2y + 3 = 19
• B. y = 0 and x = 4, 4(4) + 2y + 3 = 19
• C. y = 2 and x = 3, 4(3) + 2y + 3 = 1
• D. y = 4, x = 2, 4(2) + 2y + 3 = 19

Only the third option has a y value that is comparable to the value in the computations, according to the calculations.

As a result, the letter C is the correct response.
