Solve the equations below. with explanations .
a. y = -2x – 4
y = 5x + 5

b. -3x + y = 8
2y = 6x – 10

c. 2y = 4(x + 3)
y – 2x = 6
d. x + 2y = 4
4x – 2y = 16

Step-by-step explanation:

y=-2x-4

y=5x+5

-2x-4=5x+5

-2x-5x-4=5

-7x-4=5

-7x=5+4

-7x=9

x=9/-7

x=-9/7

y=5(-9/7)+5

y=-45/7+35/7

y=-10/7

x=-9/7, y=-10/7. (-9/7, -10/7).

-3x+y=8

2y=6x-10

6x-2y=10

-3x+y=8

y=8-(-3x)=8+3x

6x-2(8+3x)=10

6x-16-6x=10

-16=10

no solution

No Solution

2y=4(x+3)

y-2x=6

y=4x+12

y=2x+6

4x+12=2x+6

4x-2x+12=6

2x+12=6

2x=6-12

2x=-6

x=-6/2

x=-3

y=2(-3)+6=-6+6=0

x=-3, y=0. (-3, 0).

x+2y=4

4x-2y=16

5x=20

x=20/5

x=4

4+2y=4

2y=4-4

2y=0

y=0/2

y=0

x=4, y=0. (4, 0).

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
