Answer:
Step-by-step explanation:
remeber is (x,y) so it will be like this 
We can create equations to solve this.
2.50p + 1.50m = 29.50
p + m = 15
Solve for a variable in the 2nd equation and use the substitution method to solve.
p + m = 15
Subtract p to both sides:
m = -p + 15
Plug in -p + 15 for m in the first equation.
2.50p + 1.50(-p + 15) = 29.50
Distribute:
2.50p - 1.50p + 22.50 = 29.50
Combine like terms:
p + 22.50 = 29.50
Subtract 22.50 to both sides:
p = 7
Now plug this into any of the two equations and solve for the other variable.
p + m = 15
7 + m = 15
Subtract 7 to both sides:
m = 8
So he purchased 7 pineapples and 8 mangos.
Answer:
No
Step-by-step explanation:
7x2=14, 14+2=16, 16 is not 0.
Since you have two numbers that have a (x) at the ends of them, you add those first then add seven which will end up being 9x+7
Y=3x
or
-6x + 2y= 0
hope this helps and maybe brainly!
