x=7
Step-by-step explanation:
Begin by subtracting 17 from both sides of the equation:
17-5x=-18
-17 -17
You should be left with -5x=-35
Divide each side of the equation by -5 in order to get x alone
-5/-5x=-35/-5
The equation should be as follows
x=7
The answer is positive because when you divide a negative by another negative, they cancel out and make a positive
You can double check this answer by plugging in 7 for x
17-5(7)=-18
17-35=-18
-18=-18
