Quiz 2-3 Day 63 (alg2)

What is the value of x? (just x)

what is the value of y? (Just y)

What is the value of y? (Be careful! You are welcome!)

Use elimination to solve the system of equations:
3x + y = –14
–2x – y = 9

• (-5, 1)

• (5, -1)

• (-5, 4)

• (-1, 4)

Solve the system of Equation (Elimination Method)
5x + y = 9
10x − 7y = −18

• (-4,-1)
• (-1,-4)
• (4,1)
• (1, 4) 

Choose the option that will eliminate one of the variables.

3x - 4y = 16

7x + y = 19

• multiply the top row by 4

• multiply the top row by -4

• multiply the bottom row by 4

• multiply the bottom row by -4

What is the value of y?

What is the value of x?
