Equation 1) 4x + 2y = 8
Equation 2) 16x - y = 14
Multiply all of equation 2 by 2.
2) 2(16x - y = 14)
2) 32x - 2y = 28
1) 4x + 2y = 8
Add equations together.
36x = 36
Divide both sides by 36.
x = 1
Plug in 1 for x in the first equation.
4x + 2y = 8
4(1) + 2y = 8
4 + 2y = 8
Subtract 4 from both sides.
2y = 8 - 4
2y = 4
Divide both sides by 2.
y = 4/2
y = 2
So, x = 1, y = 2

If general form means y=mx+b form then your answer would be B
Answer:
A
Step-by-step explanation:
The first one is -2x + 3
The seconf one is -2x +7
Look, same slope.
Answer:
-4y=40
y=-10
x-3(-10)=17
x-30=17
x=17+30
x=47
