Answer:
= - 12
Step-by-step explanation:
Given that:
= 3(x - 4) + 2x - x2
Now put x=5
= 3(5 - 4) + 2(5) - (5)^2
= 3(1) + 10 - 25
= 13 - 25
= - 12

Answer:
45
Step-by-step explanation:
x/3=15
Mutiply each side by 3
x=45
Try this:
21/7=3
multiply 3x2
x=6
y=21 x=6
or...
7/2=21/x
cross multiply to get 7x=42
divide by 7 and x=6
