Answer:
y = 5x - 5
Step-by-step explanation:
Since y = mx + b is the slope-intercept form, we’ll need to make y alone without any coefficient
15x - 3y = 15
To do this, divide all terms by 3
15x/3 - 3y/3 = 15/3
5x - y = 5
Then make y the subject
y = 5x - 5
Hi!
Since you’ve been left with x’s on both sides of your equation, you would now want all of your x’s on one side. Since it would be easiest to get rid of the -3x on the right, you would add 3x on each side of the equation. This would result in your equation now being 10x=120. To get x on its own, you need to divide each side by 10, giving you x=12 as your final answer. Hope this helps!! :)
