Solving Systems of Linear Equations

Solve each step by graphing
y = -2/3x
2x+3y = 5

Answer:

Solve each system by substitution. Determine whether the equations are independent, dependent or inconsistent
x= y + 3
3x - 2y =4

Answer:

Solve each system by substitution. Determine whether the equations are independent, dependent or inconsistent

2x - y = 4
2x - y = 3

Answer:

Solve each system by substitution.

x + 3y = 2
5x - 20y = 5

Answer:

Solve each system addition.
x + y = 13
22x + 36y = 356

Answer:

Solve each system addition method. Determine whether the equations are independent, dependent, or inconsistent.

-3x + 2y = 8
3x + 2y = 8

Answer:

Solve each system by the addition method.
3/7x + 5/9y = 27
1/9 x + 2/7 y = 7

Answer:

Solve each system by substitution or addition, whichever is easier.
2y -x = 3
x=3y - 5
