Answer:
x= -14
Step-by-step explanation:
-x+8+3x=x-6
The first step is to simplify both sides
8+2x=x-6
Now you want to put all the xs on one side and the other like terms on the other side (Subtract both sides by x and subtract both sides by 8 so the x is alone on one side)
x= -14

Answer:
Priya's age = 15
Amirah's age = 19
Shirley's age = 13
Step-by-step explanation:
Let x be the age of Priya.
According to the question,
Amirah's age = x + 4
Shirley's age = x - 2
Their sum is 47.
So,
x + 4 + x + x - 2 = 47
3x + 2 = 47
3x = 47 - 2
3x = 45
x = 45/3
x = 15
So,
Priya's age = 15
Amirah's age = 15 + 4 = 19
Shirley's age = 15 - 2 = 13
