Question

If BC = 2x + 1, CD = 3x - 4 and BD = 22, find the value of x.

Answer 1

if BD =22
(2x+1)+(3x-4)=22
2x+1+3x-4=22
5x-3=22
5x=25
x=5

Answer 2

thanks alot also using the value of x,find BC and CD

Answer 3

if x=5
BC=11
CD=11

Answer 4

If AB = 5y - 4, BD = 7y + 3 and AD = 20y - 9, find the value of y.
Use the value of y, to find AB, BD and AD.

Answer 5

5y-4+7y+3=20y-9
12y-1=20y-9
12y-20y=-9+1
-8y=-8
y=-1
AB=-9
BD=-4
AD=-29
