Choose a variable to isolate and what it is equal to in the system of equations below? 4x=y+4
4y=3x-1
(a) 4y=4x-1
(b) y=4x-4
(c) y=4x+3
(d) 2y=x-3

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

the answer is the third / last answer

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

step-by-step explanation:
