The value of x if the sides are congruent is 3

How to determine the congruent sides?

The given parameters are

MN=6x-1 and MP=3x+8

For the sides to be congruent, then the following equation must be true

MN = MP

This gives

6x - 1 = 3x + 8

Collect the like terms

6x - 3x = 1 + 8

Evaluate the like terms

3x = 9

Divide by 3

x = 3

Hence, the value of x if the sides are congruent is 3
