Answer:
x=4
Step-by-step explanation:
4x=8x-16
(plus both sides by 16 and minus both sides by 4x)
16=4x
(divide 16 by 4 )
x=4
Step-by-step explanation:
X + Y = -3
X + 3x +5 = -3
X=-2
X+Y=-3
Y=-3+2
Y=-1
Equation 1) y = 3 - x
Equation 2) 8x + y = -4
Rearrange equation 1 so that x and y are on the same side. To do so, you add x to both sides.
1) x + y = 3
2) 8x + y = -4
Subtract equations from each other.
-7x = 7
Divide both sides by -7.
x = 1
Plug in 1 for x in the first equation.
y = 3 - x
y = 3 - 1
Simplify.
y = 2
(1, 2) ==> x = 1, y = 2
