PT = TQ

Given PT = 4x - 6 and TQ = 3x + 4

so

4x - 6 = 3x + 4

Subtract 3x from both sides

4x - 6 - 3x = 3x + 4 - 3x

Simplifying

x - 6 = 4

Add 6 to both sides

x - 6 + 6 = 4 + 6

Simplifying

x = 10

PT = 4(10) - 6 = 40 - 6

PT = 34

Answer

PT = 34

You do 4x-6=3x+4 to find the value of x. Once you figure that out you input the number u got for X into the expression. so 4(x)-6 and get that answer for PT. same applies to TQ
