Solving Systems

Is it a solution?

100

Find if (1, 2) is a solution this equation:

y= 3x - 2

No!

200

Find if (1, 1) is a solution this equation:

y= 4x - 3

Yes!

300

Find if (1, 0) is a solution for BOTH of these equations:

y =  x - 1

y = 2x

No! 

It works for the 1st, not the second

400

Find if (2, 3) is a solution for BOTH of these equations:

y =  2x - 1

y = x + 1

Yes!!

500

Find if (2, 1) is a solution for BOTH of these equations:

y =  x - 1

y = x + 1

No! It works for the first, not the second!

Solving Systems by Substitution Simple

100

Solve for x by substitution:

y = -3

2x + y = 21

x = 12

200

Solve for y by substitution:

2x + y = 5

x = -10

y = 25

300

Solve for y by substitution:

y = 7x - 10

x = -3

y = -31

400

Solve for y by substitution:

x + 2y = -20

x = 2y

y = -5

500

Solve for x by substitution:

y = 4x

2x + y = 24

x = 4

Solving Systems by Substitution Complex

100

Solve for y by substitution:

x = -5

2x + y = 21

y = 31

200

Solve for y by substitution:

x + y = -1

x = y - 3

y= 1

300

Solve for y by substitution:

2x + 3y = -1

x = y + 1

y = -3/5 or -.6

400

Solve for y by substitution:

2x + 3y = 12

x = y + 1

y = 2

500

Solve for x by substitution:

y = 6x - 12

y = -6x

x = 1
