if you isolate y in the top equation to get y=5x+6 then you can substiture y for 5x+6 in the bottom equation because thats what y equals
as of now you have -3x+6(5x+6)=-12 but if you use the distrubite property you would get -3x+30x+36=-12
then if you subtract 36 from both sides you would get -3x+30x=-48 then combine like terms to get 27x=-48 then divide both sides by 27 to get 
or x≈1.8

Answer:
<em><u>An</u></em> equation is y = 2x + 4.
Step-by-step explanation:
<em><u>ANOTHER</u></em> equation is y - 2 = 2(x + 1)
Answer:
1 : 4 , 1 : 4
Step-by-step explanation:
= 3 : 12 , 48 : 192
= 3/12 , 48/192
= 1/4 , 1/4
= 1 : 4 , 1 : 4
