Answer:
Step-by-step explanation:
3(2x - 8) + 4x = -2(12 - 7x) - 4x
6x - 24 + 4x = - 24 + 14x - 4x
10x + 24 = 24 + 10 x
Answer:
<h3>x=9</h3><h3>y=12</h3>
Step-by-step explanation:
Plug x as 2y-15 in the first equation and solve for y.
-5(2y-15)+4y=3
-10y+75+4y=3
-6y+75=3
-6y=-72
<em>y=12</em>
Plug y as 12 in the second equation and solve for x.
x=2(12)-15
x=24-15
<em>x=9</em>
X+y=-1/3
x-y=18
solve the system of equation:
equation 1 + equation 2: 2x=17&2/3=16&5/3
x=8&5/6
y=-1/3 -8&5/6=-8&7/6=-9&1/6
x=
