Answer:
x= - 3 and y= - 7
Step-by-step explanation:
Move all terms that don't contain <span>xx</span> to the right side and solve.<span>
Which gets you, x=<span><span>10/7</span></span></span>
Step-by-step explanation: Let
Let
y
be the total fee, and
x
the number of months.
Equation 1:
y
=
50
+
55
x
Equation 2:
y
=
200
+
45
x
Solve the system for
x
and
y
:
50
+
55
x
=
200
+
45
x
10
x
=
150
x
=
15
y
=
200
+
45
(
15
)
y
=
875
∴
The total amount paid to both gyms is equal after
15
months and will be
$
875
.
Hopefully this helps!
It would be 40% because those percentages added up would be 90
