Answer:
t=c+40
Step-by-step explanation:
t = total
c= the number of Cds she has
40= plus the cds she already has
t=total
well the original amount didn't change so "c" stays the same.
and we just add a constant since she just won 40 CDs with nothing more.
so
2x + 4y = 4
-8x + 8y = -16.
We can find an equivalent system by multiply the 2 equations by 2.
x + 2y = 2 multiplied by 2 is 2x + 4y = 4.
16
x=2. y=4
following bodmas
2*4=8
