Which is a pair of equal expressions? A. 9y+ 6 and 6y + 9
B. 7x-3 and 3-7x
C. 2y x 4 and 2 x 4y
D. 5x - 10 and 5(2-x)

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
