12x+15y=34
2(-6X+5Y)=3
12x+15y=34
-12x+10y=6 = 25y=40 25/40 =0.25 then you plug that back into any original equation and you get the x
Answer:
24 Cupcakes remain
Step-by-step explanation:
One dozen is 12
12 times 6 is 72
72 divided by 3, to find one third is 24
One third remains, so your answer is 24
24x-1+20x+5=180
44x+4=180
44x=176
x=4
Therefore, 20x+ 5 is equivalent to 20(4)+5
20(4)+5
80+5
85
