From the second equation ,we can know that y=3.25x+0.75
plug it into the first equation
-4.5x-2(3.25x+0.75)=-12.5
-4.5x-6.5x-1.5=-12.5
-11x=-11
x=1
plug it back into the second equation, y=3.25x+0.75=4
the answer would be (1,4)

Step-by-step explanation:
3/22 hope that helps have a good one
{1,3,5}
ie, sub 1, 3 and 5 for x and see which one is true
20-2(1)=10
20-2=10
18=10
false
20-2(3)=10
20-6=10
14=10
false
20-2(5)=10
20-10=10
10=10
true
answer is 5
Answer:
x = 30
Step-by-step explanation:
6(x-2)=8(x-9)
6x-12=8x-72
6x-6x-12+72=8x-6x-72+72
60=2x
x = 30
check:
6(30-2)=8(30-9)
6(28)=8(21)
168=168 ✅
