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
