1 / 10

Solve the system of equation. Use the elimination method.

5x - 4y = 6

x + 2y = 4

2 / 10

Solve the system of equation. Use the elimination method.

2x + 7y = 6

2x + 7y = 8

3 / 10

Calculate x, y and z:

x + 2y - 5z = -11

4x - 3y + 2z = 11

-3x + 5y + 3z = 8

4 / 10

If two lines are parallel, then they have -

5 / 10

The total number of the value of y, so that (1+y) p + 8q = 4y, kp + (k + 3) q = 3k−1 system of the equations has infinitely many solutions.

6 / 10

Solve the system of equations. Use the Substitution method.

x + y = 7

x - 2 = 3

7 / 10

When solving a system algebraically (substitution/elimination), what are we trying to find?

8 / 10

If we are solving the system using the substitution method, what would be the best first step?

y =7x +15

-2y - 5x = -11

9 / 10

Solve the system of equations. Use the elimination method.

a – 9b = 18

3a – 27b = 27

10 / 10

When solving a system by graphing, what do we look for?
