Answer:
(-7, -10)
Step-by-step explanation:
Solve for x and y in double variable equation
y = 2x + 4
y = x - 3
y = x - 3, plug in to first equation
x - 3 = 2x + 4
x = -7
y = -7 - 3
y = -10
(-7, -10)
You can use a guess and check method.
We know .50halfdollar
we know .05 nickels
.50(26) + (.05)(8)=$13.40
13.00+.40=13.40
