Best Answer

The solution pair is (-7, 22), demonstrated as follows:

(1) x + y = 15 : given;

(2)4x + 3y = 38 : given;

(3)3x + 3y = 45 : equation (1), multiplied by 3;

(4) x = -7 : equation (2), minus equation (3);

(5) y = 22 : equation (1), minus equation (4).

Q: The order pair for x plus y equals 15 and 4x plus 3y equals 38?

(1) x+y=15(2) 4x+3y=38From (1) one gets x=15 -y, put into(2)4(15-y)+3y=3860-4y+3y=3860-y=38y=22 then x=15-y=-7(-7,22) is the solution

It equals 285
