Question

Solve each system by elimination.
1) –3x – 6y= -3
5x + 5y=0

Answer 1

Answer: x=−1 and y=1.

Step-by-step explanation: −3x−6y=−3;5x+5y=0

5(−3x−6y=−3)

6(5x+5y=0)

−15x−30y=−15

30x+30y=0

15x /15 = −15 /15

x=−1

−3x−6y=−3

(−3)(−1)−6y=−3

−6y+3+−3=−3+−3

−6y /−6 = −6 /−6

y=1

x=−1 and y=1
