Answer:
x = 3.5
y = 11.75
Step-by-step explanation:
-9x - 2y = -55
6x - 4y = -26
Step 1:
-2(-9x - 2y = -55) → 18x + 4y = 110
Step 2:
18x + 4y = 110
<u> 6x - 4y = -26</u>
<u> 24x </u>= <u>84</u>
24 24
x = 3.5
Step 3:
6(3.5) - 4y = -26
21 - 4y = -26
<u> -21 -21 </u>
<u> -4y </u>=<u> -47</u>
-4 -4
y = 11.75
