1. 8x+15=dx-20 2. 12(7+2y)=4y-(3-ty)

3. 15+x(3t-4)=8(-2t+11)

:) answer all for brainliest

8x+15=dx-20

8x+15+20=dx

8x+35=dx

d=8x+35 /x

12(7+2y)=4y-(3-ty)

12(7+2y)=4y−3+ty

12(7+2y)−4y=−3+ty

12(7+2y)−4y=ty−3

12(7+2y)−4y+3=ty

t= 12(7+2y)−4y+3 /y

15+x(3t-4)=8(-2t+11) SOLVING FOR X

15+x(3t-4)=8(-2t+11)

x= 8(−2t+11)−15 /3t−4

x= −16t+73 /3t−4

Hope this helps!God bless you and have a wonderful day!

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
