2x - 4/5 = x + 4

You have to do -x to both sides

2x - x - 4/5 = x - x + 4

x - 4/5 = 4

Then you add 4/5 to both sides

x - 4/5 + 4/5 = 4 + 4/5

x = 24/5

Then we need to check are work by plugging it in

2(24/5) - 4/5 = 24/5 + 4

48/5 - 4/5 = 24/5 + 4

44/5 = 24/5 + 4

44/5 = 44/5

So <em>x </em>= <em>24/5</em>

Rewrite the following equation in slope-intercept form.

Tamiku [17]

Hi there!

Slope intercept form is $y=mx+b$ . To do this, we just need to isolate y. This can be done by first moving everything that doesn't involve a y to the other side, and then dividing by the coefficient:

$16x+17y=-2$

$17y=-2-16x$

$y=-\frac{2}{17}-\frac{16}{17}x$

And there you have your answer, just above.

Hope this helps, feel free to let me know if you have any additional questions about this specific problem!
