Answer:
(3,10)
Explanation:
1. 5x - y = 5 change this eqaution, mainly because it's easier
1. b. y = -5 + 5x substitute this for y
2. 3x + 2y = 29
3x + 2(-5+5x) = 29
3x -10 + 10x = 29
13x - 10 = 29
+ 10 +10
13x = 39
divide by 13 on both sides
x = 3
put x back in the second equation
5 (3) - y = 5
15 - y = 5
-15 -15
-y = -10
divide the negative
y = 10
check it...
3 (3) + 2 (10) = 29
9 +20
= 29 it is checked and correct
