Answer:
Given the system of equation:
.....[1]
......[2]
Equate these two equations we get;
Subtract 8x to both sides we have;
Add 40 to both sides we have;
Using the identity rule:
then;
⇒
Add 5 to both sides we have;
x = 5
Substitute this value in [2] we have;
y=8(5)-40 = 40-40 = 0
therefore, the solution(s) of the system of equations is, (5, 0)
0=0
Step-by-step explanation:
$252.5
45(4.5)+50
202.5+50
=252.5
