Systems of Equations by 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)

3x + y = 1
y = 4x + 1

• (0, -1)

• No Solution

• (0, 8)

• (0, 1)

y = x +1

-2x + 2y = 1

• Infinitely Many Solutions

• No Solution

• (1,2)

• (2,1)

What is the first step?

• 7(2y - 4) - 2y = 5

• 7x - 2(2x - 4) = 5

• 7(2x - 4) - 2y = 5

• 7x - 2y = 2x - 4

• No solution

What is the first step?

• x = 6(8x + 1) + 3

• y = 8(6x + 3) + 1

• y = 6(8x + 1) + 3

• 8x + 1 = 6x + 3

• x = 8(6x + 3) + 1

x = -3y - 13

4x + 2y = 4

What is the first step?

• 4(-3y - 13) + 2y = 4

• 4(-3x - 13) + 2y = 4

• 4x + 2(-3y - 13) = 4

• 4x + 2(-3x - 13) = 4

• -3y - 13 = 4x + 2y

Find the solution to the system.
y = x-6
y = -3x + 2

• (0, -6)

• (6, 0)

• (-4, 2)

• (2, -4)

What is the solution?

• (1, -1)

• (-1, 1)

• (0, -2)

• (0, 1)
