Question 815083: Solve using elimination method
1) 9x-y=0
x+4y=37
The solution is ?
2) Solve by elimination
8x+4y=0
-8x+y=20
The solution is ?
3) Solve by elimination
2x-y=-3
x+6y=44
The solution is ?
4)Solve by elimination
7x/2 +7y/3 =91/6
x/4 + y/3 = 17/12
The solution is ?
5) A company produces two models of strollers, model 501 and model 601. Model 501 requires 2 hours of assembly time and model 601 requires 4 hours of assembly time. The parts for model 501 cost $30 and the parts for model 601 cost $40. If the company uses a total of 60 hours of assembly time and spendss $680 per days for these two models, how many of each type are made in a day?
How many 501 strollers are made in one day?

======================
Solve using elimination method
1) 9x-y=0
x+4y=37
---------------
To eliminate one of the variables, multiply 1 or both equations to make the coefficients match.
Mupltiply the 1st eqn by 4
36x- 4y = 0
x + 4y = 37
--------------- Add
37x = 37
x = 1
---
x + 4y = 37
y = 9
==========
Do the others the same way.
PS "The solution is?" serves no purpose and is irritating.
