When it comes to fractions yes you do. But to make it easier just multiply the denominators and that should give u a common denominator, they don't always have to be least common.
I suggest using an app for math to solve problems like this they r helpful for example PhotoMath and Socratic
Answer:
y =

+
Explanation:The slope-intercept form of the equation has the following formula:y = mx + c
where:
m is the slope
c is the y-intercept
The given is:17x + 15y = 5
To put it in the slope-intercept formula, we should isolate the y as follows:17x + 15y = 5
15y = -17x + 5
y = (-17/15) x + (5/15)
y =

+

where:
m is the slope = -17/15
c is the y-intercept = 1/3
