Linear Equations

 $y=-7x-4$  

 $y=-x+2$  

Solve the system of equations

•  $\left(-1,3\right)$  

•  $\left(3,-1\right)$  

•  $\left(1,3\right)$  

•  $\left(3,1\right)$  

Given this system of equations:

200A + 150B = 1000

25A +50B = 2500

Where would you like to start?

• Solve for A in the first equation

• Solve for A in the second equation

• Solve for B in the first equation

• Solve for B in the first equation

Solve the system of equations by substitution

y = 4x+1

3x + 2y = 13

• (1, 5)

• (5, 1)

• (0.25, 2)

• (2, 0.25)

What is the solution to the system of equations?

• (-3, 4)

• (3, 4)

• (-4, 3)

• (4, 3)

Answer explanation

You know what seems odd to me?

Numbers that can’t be divided by two.

Solve the system of equation using substitution.
y = 8x + 2
y = -x - 7

• (1, 10)
• (-1, -6)
• (2, 7)
• (9, 9)
