Answer:
(74/9,274/9)
Step-by-step explanation:
You have
x-5y=4 and
y=2x+14
so we subsitute y in the first equation
x-5(2x+14)=4
x-10x-70=4
-9x=74
x=74/9
so y=2(74/9)+14
y=148/9+14
y=274/9
so the oredered pair is
(74/9,274/9)

Answer:
<h3> -8(2x +x )/-2y = - 30</h3>
Step-by-step explanation:
x=-5, y=2 and z=0
-8(2x +x )/-2y =(-8•3x)/-2y = [-8•3(-5)] / (-2•2) = 120/(-4) =-30
