since these two angles are the same, we can write down following equation:
70=x+20
then x = 50
answer is 31
Step-by-step explanation:
You need to make one of the terms the same.
I will make the "2y" in the second equation 4y because it's a multiple of it
To change 2y to 4y, multiply the entire second equation by 2.
2(4x+2y=28)
8x+4y=56
Now subtract the first equation from the second equation-
8x+4y=56
-5x+4y=38
3x=18
x=6
Plug in x for y-
5(6)+4y=38
30+4y=38
-30 -30
4y=8
/4 /4
y=2
So your answer is x=6, y=2.
(6,2) if needed in point form.
Step-by-step explanation:
Convert the equation to the slope-intercept form (y = mx + b):
<em>add x to both sides</em>
<em>divide both sides by (-2)</em>
Choose any three values of x and calculate the values od y:
for x = 0
for x = 4
for x = 10
