System of Equations Substitution Easy

Which option shows the CORRECT substitution for this system?

Which option shows the CORRECT substitution for this system?

If a system of equations has infinitely many solution, what does the graph look like?

• intersecting lines

• parallel lines

• one horizontal and one vertical line

• coinciding lines (overlapping)

Solve the following system.

y=4

x=3y+5

• (27,4)

• (12,4)

• (17,4)

4x + 2y = -6
y = -8

• (16, -8)

• (-8, 16)

• (2.5, -8)

• (-8, 0)

Solve the system of equations.

• (11, 21)

• (3, 11)

• (11, -67)

• No solution

• Infinite solutions

Solve the system of equations.

• (-7, 8)

• (-7, -6)

• (8, -7)

• No solution

• Infinite solutions

-5x - 4y = -9
y = 6

• (3, 6)

• (-3, 6)

• (6, -3)

• (6.8, 3)

Substitution method for solving systems of equations includes...

• two or more linear equations

• solving for one variable, then substituting the number into the other equation

• answers 1 and 2

• solving for only x, then using the number as the only solution for x and y

Consistent is defined as...

• a system of equations that has many possible solutions

• a system of equations that has at least one solution

• a system of equations that has no solutions

• a system with an independent variable only
