7x + 2y = 17

(3x + 2y = 3)

Step-by-step explanation:

Multiply second equation by - 1

-1 * (3x + 2y) = 3

-3x - 3y = - 3 now add this to the first equation

7x + 2y = 17

(-3x-2y) = - 3

7x + 2y - 3x - 2y = 17 - 3 (2y will eliminate - 2y)

4x = 14

x = 7/2 now by using this information we found we can calculate the value for y

if 3x + 2y = 3 (replace x by 7/2)

3 * (7/2) + 2y = 3 ➡ 21/3 + 2y = 3 ➡ 2y = 3 - 21/3 ➡ 2ty = 15/2 ➡ y = 15/4
