So I've been missing so much school. cause family issues. and the ONLY way i can pass is if i get my homework turned in. SOOOO i need your help with math. Lol. expalin to me how to do it.

Rewrite the following equation in standard form (Ax + By = C). Show your work.
3y = -2x - 5
5y = 12 + 4x
11 - 3x = y

Rewrite each equations in slope-Intercept from (y = mx + b). Show your work.
4x - 2y = -20
-y = 8 - 3x
3y - 18 = 9x

Use graphing methods to find the solution for each of these system of linear equations.
y= -6x + 9
and
y = 4x - 11
Point of intersection:___________________
2x + y = 12
and
-5x + 5y = 15
Point of intersection:___________________

Solve each of the following systems of equation symbolically. state the method you are using (equivalent forms, substitution, combination). SHOW ALL YOUR WORK CLEARLY.
{4x + 2y = 10
{2x - 2y = 14

{2x + 10y =36
{y = x + 12

{y = 7x + 4
{y = 9x - 6

For the application below....
1. define the variable
2. write a system of equations
3. solve the ytem by any method - show your work
4. write a sentence to answer the question

For a charity fundraiser, student sell button for $2.50 each and t-shirts for $10.00 each. If Scott sells 50 items and has an income of exactly $410.00, how many button and how many t-shirts did he sell?
