Knowing that there are two logs on both sides of the brackets, they cancel out.
This leaves:

4y-1=2y+7 (solve for y)
4y-2y=7-1
2y=6
y=3

Hope this helped :)

Use substitution method <br>3x +4y+175x-2y=11

Viefleur [7K]

$3x +4y+175x-2y=11$

$4y-2y+175x+3x=11$

$2y+178x=11$

$2y=11-178x$

$y=\frac{11-178x}{2}$

$y=-89x+\frac{11}{2}$

$178x=-2y+11$

$x=\frac{-2y+11}{178}$

$x=\frac{-1}{89} y+\frac{11}{178}$

I need help ASAP!!!!

Ad libitum [116K]

Step-by-step explanation:

Kindly find 4 attached files

The proportionality is determined by the lines that only passes through the origin

And all the lines drawn are passing through the origin

So by either one of the 2 ways

By using rule of direct variation y=kx that has no y intercept

Or by finding the equation of straight line and find the slope with neglecting the y intercept since it's 0

How to write this standard form?<br><br> 2y=-3x+5

Schach [20]

Answer:

3x + 2y - 5 = 0

Step-by-step explanation:

Standard form: ax + by + c = 0

2y = -3x + 5

+3x - 5 to both sides

2y + 3x - 5 = 0

Change order.

3x + 2y - 5 = 0
