Answer:
x=2
Step-by-step explanation:
y=-7x+13
y=-1
plug in -1 for y in the first problem.
-1=-7x+13
subtract 13 by both sides
-14=-7x
divide both sides by -7 to isolate x
2=x

Each smaller donation was for $20 The largest donation was $15 greater than the smaller donation. First, determine the size of each donation. Since they are in a ratio of 4:4:7, it's easiest to add the ratios together (4+4+7) = 15. Then divide the total donation by that sum (75/15) = 5. Finally, multiply 5 by each of the ratios. 5 * 4 = 20, 5 * 4 = 20, and 5 * 7 = 35 So the 2 smaller donations were $20 each, and the largest donation was for $35. The largest donation was $35 - $20 = $15 larger than one of the smaller donations.
