Answer:
= 14/3
Step-by-step explanation:
add 3 to both sides of the equation
-7x+14y=-14
-3x+7y=-3
when using elimination you need to multiply or divide one equation to be able to “eliminate” a variable.
-7x+14y=-14
-2(-3x+7y=-13)
multiply the second equation by -2
-7x+14y=-14
6x-14y=6
simplify
-1x=-8
divide by -1 on both sides to isolate the x
x=8
now you can plug in 8 for x in one of the equations.
-3(8)+7y=-3
simplify
-24+7y=-3
add -24 to both sides the isolate the constant and variable
7y=21
now divide by 7 on both sides to isolate y
y=3
this system of equation had one solution at (8, 3)
i hope this helps :)
The answer is C.
Explanation:
If you were to buy 5 games and they all cost $69.99 and you want to know to total cost, you would do $69.99 x 5 or count $69.99 five times.
