I would use elimination
2x+3y = 7
2x-y = -5
Subtract those equations
4y = 12
Y = 3
Now plug in 3 for any y value
2x - 3 = -5
2x = -2
X = -1, y = 3
Answer:
see below for a graph
Step-by-step explanation:
The equation is in slope-intercept form, so right away you know one point is the y-intercept: (0, -4).
Another point can be found using the slope, which is 3/2, to go 2 units to the right and 3 units up. (Slope = rise/run, so rise = 3 and run = 2 match the slope.)
Answer:
$2
Step-by-step explanation:
You can solve this quickly by finding the difference in prices first.
7.49 - 6.99 = .50 difference
Now - multiply 4 shirts by .50 = $2
That is the SAVINGS for 4 shirts at the cheaper place
