Please help. You will get some points.

1) x: small #; y: large #

4y = 7x

x + y = 22

-7x + 4y = 0

x + y = 22

---multiply the second equation by -4

-7x + 4y = 0

-4x - 4y = -88

solve

-11x = -88

x = 8

---substitute with any of the equation above i chose the very first one

4y = 7(8)

4y = 56

y = 14

x = 8; y = 14

2) x = small #; y = large #

y - x = 15

5x = y - 9

after rearranging, solve

-x + y = 15

5x - y = -9

-4x = 6

x = -1.5

substitute

-(-1.5) + y = 15

1.5 + y = 15

y = 13.5

x = -1.5; y = 13.5

3) x = lemon cream; y = fudge cookie

3x + 2y = 400

2x + 3y = 425

multiply the first equation by -2, multiply the second equation by 3

-6x - 4y = -800

6x + 9y = 1275

solve

5y = 475

y = 95

substitute

3x + 2(95) = 400

3x + 190 = 400

3x = 210

x = 70

x = 70; y = 95

can i see the following ?

step-by-step explanation:

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
