Answer:
(- 8, 8 )
Step-by-step explanation:
Given ( ?, 8 ) is a solution. To find x substitute y = 8 into the equation, then
- 4x - 8 = 24 ( add 8 to both sides )
- 4x = 32 ( divide both sides by - 4 )
x = - 8
Thus solution is (- 8, 8 )

-x+4=2x+1
4-1=2x+x
3=3x
x=1
y=-1+4
y=3
Answer:
3.5
Step-by-step explanation:
These are similar triangles.
BC:AC = BD:AD
6:5 is the ratio.
Then, simply multiply:
4.2 x 5/6 = 3.5
So, x = 3.5!
