5 ( x + 3) = 6x - 3
5x + 15 = 6x - 3
x = 18 <====== this is the number
Y= 1x + 2
Use the formula y=mx+b when trying to do things like this.
Y intercept form is when your line intersects through the y axis, and this is also your b. M is your slope.
4.5 is the answer.
First you multiply 9.6x3.2 which gives us 30.72
Then you divide 138.24 by 30.72 which equals 4.5
Hope this helps
