Answer:

x = 6

Step-by-step explanation:

141 = (13x + 4) + (10x - 1)

141 = 13x + 10x + 4 -1

141 = 23x + 3

141 - 3 = 23x

138 = 23x

138 ÷ 23 = x

6 = x

Answer:

x = 6

Step-by-step explanation:

You know that PQR = 141.  Angle PQR is made up of angles PQS and SQR.  This means that you can add up the two angles, set it equal to PQR, and solve for x.

PQR = PQS + SQR

141 = 13x + 4 + 10x - 1

141 = 23x + 3

138 - 3 = 23x + 3 - 3

138 = 23x

138/23 = 23x/23

6 = x
