Answer:
x=60, y=30
Step-by-step explanation:
4x-7y=30
4x-5y=90
Subtract the equations
4x-7y=30-4x-5y=90
=2y=60
Solve 2y=60
Divide both sides by 2
2y/2=60/2
Simplify;
y=30
For 4x-7*30=30 for x
4x-7y*30=30
Multiply the numbers:7*30=210
4x-210=30
Add 210 to both sides
4x-210+210=30+210
Simplify;
4x=240
Divide both sides by 4
4x/4=240/4
Simplify
x=60
The solutions to the system of equations are:
x=60, y=30

Answer:
580 is spent on onions and potatoes
Step-by-step explanation:
The grocery store ordered 47 bags of onions, and 1 bag costs 2.
It also ordered 167 bags of potatoes, and the bag costs 3.
47 bags onions X 2 render 94
162 bags potatoes X 3 render 486
94 (cost of onions) + 486 (cost of potatoes) = 580
Well, to solve, you would subtract 8 from both sides, which means x would end up equaling 32.
X=32
