Trust me this is the answer 18.666666
2x - 3y = -12 ⇒ 2x - 3y = -12⇒ 2x - 3y = -12
x + y = 1 ⇒ 2(x + y) = <u>1⇒ 2x + 2y = 1</u>
y = -11
2x - 3y = -12
2x - 3(-11) = -12
2x + 33 = -12
<u> - 33 - 33</u>
2x = -45
<u> 2x</u> = <u>-45</u>
2 2
x = -22.5
(x, y) = (-22.5 , -11)
PEMDAS
7+18/(6-3)
7+18/3
7+6
13
just multiply 45 time 31!
