Step-by-step explanation:
move all the terms that don't contain x to the right side and solve
Answer:
(2,3)
Step-by-step explanation:
x + y = 5:
2 + 3 = 5
y = 1/2x + 2:
3 = 1 + 2
Solve for a.
y=2x/a+2b
Multiply both sides by a.
ay=2ab+2x
Add -2ab to both sides.
ay+−2ab=2ab+2x+−2ab
−2ab+ay=2x
Factor out variable a.
a(−2b+y)=2x
Divide both sides by -2b+y.
a(−2b+y) / −2b+y = 2x / −2b+y
a = 2x / −2b+y
Answer:
$18
Step-by-step explanation:
100% = $12
50% = $6
$12 + $6 = $18
