Answer:
(-4, 2)
Step-by-step explanation:
4x+2y=-12
3x+y=-10
Start by dividing the first equation by 2 to simplify it...
2x+y=-6
Then, subtract -2x from both sides to isolate y...
y=-2x-6
Substitute -2x-6 for y in the second equation...
3x-2x-6=-10
Combine like terms...
x-6=-10
Add 6 to both sides
x-6+6=-10+6
x=-4
Plug -4 in for x to solve for y:
3(-4)+y=-10
-12+y=-10
Add 12 to both sides
-12+12+y=-10+12
y=2
(x,y)=(-4,2)
Answer:
Step-by-step explanation:
Simplify:
45 = 5 * 3 * 3
60 = 5 * 3 * 2 * 2
GCF = 5*3 = 15

Answer:
x = -5
Step-by-step explanation:
Note that x does not change. Hence, this line is a vertical one, and its slope is undefined. The line is defined by the equation x = -5.
