The measure of x and AT are 3.75 and 11.25
Given the following expressions
AT = 3x + 1,
TL = 15
AL = 7x+1
Using the expression
AT + TL = AL
Substitute the given expression into the formula
3x + 1 + 15 = 7x + 1
3x + 16 = 7x + 1
3x - 7x = 1 - 16
-4x =-15
x = 15/4
x = 3.75
Get the measure of AT and TL
AT = 3x + 1
AT = 3(3.75) + 1
AT = 11.25 + 1
AT = 12.25
Hence the measure of x and AT are 3.75 and 11.25
