First Let we solve the Original system of equations:
equation (1): 
equation (2): 
Multiplying equation (1) by 7, we get
Subtracting,
implies 
Then
Thus the solution of the original equation is
Now Let we form the new equation:
Equation 2 is kept unchanged:
Equation (2):
Equation 1 is replaced with the sum of equation 1 and a multiple of equation 2:
Equation (1): 
Now solve this two equations: 
Multiply (1) by 7 and (2) by 8,
Subtracting,
implies
Then x=2.
so the solution for the new system of equation is x=2, y=1.
This Show that the solution to the system of equations 8x − 5y = 11 and 7x − 8y = 6 is the same as the solution to the given system of equations
Answer:
The answer is 60
Step-by-step explanation:
if she drove 180 mile in 3 hours, you have to divide 180 by 30 to find the constant rate. 180 divided by 3 is 60
Answer:
Part A: 1.25g + 14.25 <u><</u> 55.00
Part B: 32 games
Step-by-step explanation:
A:
price per game * games played (1.25g) + money he's already spent (14.25)
must be less than or equal to his total budget (55.00)
equation: 1.25g + 14.25 <u><</u> 55.00
B:
total (55.00) - already spent (14.25) = what he can spend on games (40.75)
55.00 - 14.25 = 40.75
arcade budget (40.75) / cost per game (1.25) = 32.6
because you can't play 0.6 games, 32 games
