Question

Find a if the ordered pair (2 , a + 2) is a solution to the equation 2 x + 2 y = 10?

Answer 1

Step-by-step explanation:

From ordered pair we get: x = 2 and y = a+2

Using values in equation 2x+2y=10

$2(2) + 2(a + 2) = 10 \\ 4 + 2a + 4 = 10 \\ 2a + 8 = 10 \\ 2a = 10 - 8 \\ 2a = 2 \\ a = 1$
