Solve the System of Equations

Solve the following systems of equations using substitution:

x = 6

y = 2x - 3

• (6, 6)

• (6, 9)

• (9, 6)

• (9, 9)

Solve the system of Equation by elimination.

x + 3y = 18

–x –4y = –25

• (3,7)

• (-3,7)

• (7,-3)

• (-3,-7)

Solve by substitution.

3x + 4y =18

y=3

• (3, 2)

• (2,-3)

• (2,3)

• none of these

Is (6,3) a solution to this graph?

• Yes

• No

• Maybe

When you graph the exact same equation twice,

• you will have no solution. 

• you will have one solution.

• you will have infinite solutions. 

• you will graph a giraffe.
