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)
Answer:
Was number 11
Step-by-step explanation:
50 - 6 = 44
44 dividid 4 is 11
Ok, so assuming you know what the slope of -1 looks like
a bit like \ except more diagonal
you look for point (4,-2), then you draw the -1 slope from it
it should cross through points (5,-3) and (3,-1)
Answer:
Step-by-step explanation:
d) Let the cost of one group lesson be x and one private lesson be y
