Solving Linear Systems by Elimination

Question 1

Solve the following linear system of equations using substitution.y = 3x – 5y = 2x – 6

Revolt · Accepted Answer

(–1, –8)

Question 2

6x – 2y = 102x + 3y = 51Solving the first equation above for y gives: y = ⇒ 3x – 5

Revolt · Accepted Answer

3x - 5

Question 3

Which choice shows the result of substituting 3x – 5 into the second equation for y?

Revolt · Accepted Answer

2x + 3(3x – 5) = 51

Question 4

Solving the equation 2x + 3(3x – 5) = 51for x gives x = .
