Answer:
Step-by-step explanation:
e = earrings and b = bracelets
so each earring cost 5 bucks.....5e
and each bracelet cost 7 bucks.....7b
and she hopes to make $ 300...
so ur equation is : 5e + 7b = 300 <===
Answer:
One solution
Step-by-step explanation:
They have isolated y for you in both equations so you can plug either one into the other.
y = 3x - 1
2x + 7 = 3x - 1
isolate the x
7 = x - 1
x = 8
Go back to the original and plug 8 into x to get y.
y = 2 (8) + 7
y = 16 + 7
y = 23
This means at (8, 23) y = 2x+7 is equal to y = 3x-1. In other words they share a point at (8, 23). This is the only solution because for any other x and y they'd not be equal.
