Use substitution to solve the
following system of equations.
2x + 4y = 12 AND x=y - 3

The solution is (0, 3)

Step-by-step explanation:

First, reduce 2x + 4y = 12 to x + 2y = 6, for easier calculations.

Next, substitute y - 3 for x in the other equation:

y - 3 + 2y = 6, or

3y = 9

Then y = 3.  Since x = y - 3 in general, x = 3 - 3 = 0 when y = 3.

The solution is (0, 3)

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
