Question

6X plus 3Y equals 3 3x minus Y equals four

Answer 1

Answer:

Step-by-step explanation:

6x + 3y = 3 simplify by dividing both sides by 3 2x + y = 1

3x - y = 4 the 1st equation has a positive y, the 2nd has a negative y. Use elimination

to reduce them down to a single variable equation:

2x + y = 1

3x - y = 4

________

5x = 5 solve

X = 1 substitute back in to one of the original equations to find y

3x - y = 4

3(1) - y = 4

- y = 1

y = -1 (1,-1)
