X=20 because you add the 5 to the other five then you move the fraction down then you multiply the 2 by the 10 you got with the 5+5 earlier
Assuming one meal has been ordered for each person, let x and y represent the number of steaks and the number of chickens ordered, respectively. Then, we get the following system of linear equations. x + y = 12 (Eq. 1) 12x + 10.5y = 138 (Eq. 2) If we plug y = 12 - x, which is from Eq. 1, into Eq. 2, 12x + 10.5(12 - x) = 138 1.5x + 126 = 138 1.5x = 12 x = 8 and plug x = 8 into Eq. 1, we get y = 4. So, they ordered 8 steaks and 4 chickens.
<h3>I'll teach you how to solve x= 12 - y, 2x + 3y = 29</h3>
------------------------------------------------------------
x= 12 - y, 2x + 3y = 29
Substitute x=12-y:
[2(12-y)+3y=29]
Isolate y for 2(12-y)+3y=29:
2(12-y)+3y=29= y= 5
Substitute y=5:
x=12-5
12-5= 7
x=7
Your Answer Is (C) x=7, y=5
plz mark me as brainliest if this helped :)
