Answer:
x = 0
, y = 7/6
Step-by-step explanation:
Solve the following system:
{18 y - 12 x = 21
6 x - 9 = -9
In the second equation, look to solve for x:
{18 y - 12 x = 21
6 x - 9 = -9
Add 9 to both sides:
{18 y - 12 x = 21
6 x = 0
Divide both sides by 6:
{18 y - 12 x = 21
x = 0
Substitute x = 0 into the first equation:
{18 y = 21
x = 0
In the first equation, look to solve for y:
{18 y = 21
x = 0
Divide both sides by 18:
{y = 7/6
x = 0

Answer: {x = 0
, y = 7/6

To add 11% to an amount means to multiply the amount by 1.11.
You can start with $115 and multiply it by 1.11 eleven times.
A quicker way is to find 1.11^11 and then multiply by $115.
$115 * 1.11^11 = $115 * = 3.151757 = $362.45
