x = 
subtract 4x from both sides of the equation
6x - 4x - 2 = 13
2x - 2 = 13
add 2 to both sides
2x = 13 + 2 = 15
divide both sides by 2
x = 
Answer:
The value of x is 62°.
Step-by-step explanation:

Step-by-step explanation: Subtract 3
x from x
.
This is a ratio problem:
26/18 = 39/x
to solve for x cross multiply: 18 * 39 = 702 and then divide by 26
702 / 26 = 27
x = 27
