Opposite of 79 must add to 180 which is 101 and x is equivalent
Answer:
x=3 y=-1
Step-by-step explanation:
To get the value of x you need to put in the second equation which is y=8-3x as the y value for the first equation which is 2x+3y=3 making it
2x+3(8-3x)=3
2x+24-9x =3
24-7x =3
-7x=-21
Multiplying both sides by -7
x= 3
After getting an x value you substitute it in the equation in order to find your y value which is
2x+3y=3
2(3)+3y=3
3y=-3
Multiplying both sides by 3
y= <u>-3</u>
3
y=-1

Answer:
21
Step-by-step explanation:
3x+6=5x-4 because of alternate interior angles of a parallel line
10=2x
x=5
15+6=21
