Answer: X=22
Step-by-step explanation:
Multiply the denominator on both sides
1) x-7=15. 3(x-7/3)= 3(5) 3 cross cancel and 3(5)=15
*Tip: A shortcut is when dealing with fractions multiply the denominator on both sides to make the equation easier to solve
Isolate the variable (Add 7 on both sides)
2) X=22
