Answer:

x=3y-11

then now putting the value of x in second equation

4(3y-11)-3y =26

12y - 44-3y=26

9y=44+26

9y=70

y=70/9

now putting the value of  y in 1st equation then

x=3*70/9-11

x=37/3

now checking this is correct or not in 2nd eqn

4*37/3-3*70/9=26

148-70/3=26

26=26

Solve for c: a=7b+8c+9d-10
polet [3.4K]
<span>a=7b+8c+9d-10
a = 8c + 16d - 10
solve for c then
8c = a - 16d + 10
  c = (</span>a - 16d + 10) / 8
or
  c = a/8 - 2d + 5/4
