Step-by-step explanation:
70/3
6x > 220 - 80
220 - 80 = 140
6x > 140
Divide 6 on all terms & simplify.
6x/6 > 140/6
Divide x by 1 and cancel common factor 140/6
x > 140/6
Factor 2 out of 140
x > 2(70) / 6
Cancel common factors
Factor 2 out of 6
x > 2 • 70 / 2 • 3
Cross out both of the 2’s and rewrite expression
x > 70/3 or (70/3 , ♾ )
Start with x=y+13 then plug it in so you get 4(y+13) + 2y = 10
Then you get 4y + 52 +2y =10
Then you add you similarities to get 6y + 52= 10
Subtract 52 from both sides gets you 6y=-42. Then you divide and you get y=-7.
Then you plug that into your original equation so 4x + 2(-7) = 10
4x + -14 = 10
4x = 24
X= 6
Y= -7
The awnser is c. Hope it helps
