X-5y=-21
x=-21+5y
-6(-21+5y)+4y=10
126+-30y+4y=10
126+-26y=10
-26y=-116
y=4.4615
x=1.3076
6x+x-8=90 because right angle
7x=98 combine like terms
7x/7=98/7
X=14
m<1=6*14=84
m<2=14-8=6
Answer:

Step-by-step explanation:
On the right side of the = multiply -4 through

add 28a and add 4 to both sides


divide both sides by 22

Answer:
you put two of the equations together and then the last one there you just automatically added on
Step-by-step explanation:
4x-7y=-28
25xy

Total outcomes in which Billy can get 5 or more : 2 <u>outcomes</u>
