Answer:

x = 5/4

Step-by-step explanation:

By combining like terms, you get 8x = 10.

Divide the 8 on both sides of the equation.

x = 10/8

This, however, can be simplified by dividing by 2. This ultimately gives us 5/4.

Answer:

x=5/4

Step-by-step explanation:

Hi there! I'd be happy to help you solve this equation!

To combine the equation 3x+5x=10's "like" terms, you simply add the 3 and 5, resulting in 8, being sure not to leave out the x.

Now we're left with 8x = 10.

Solve for x: Divide both sides of the equation by 8. You can use a calculator!8x/8 = 10/8

Hence, our answer is now x = 5/4.

I hope this helped you! Comment below if you think I've made a mistake or would like further explanation! <3

HELP ME PLEASE!!!
ser-zykov [4K]

parallel lines, have the same exact slope, hmmm what is the slope of y = -2/3 x + 1/3 anyway? well, low and behold, the equation is already in slope-intercept form, therefore


\bf ~~y=\stackrel{slope}{-\cfrac{2}{3}}x+\cfrac{1}{3}~~ has a slope of -2/3.


so we're really looking for a line whose slope is -2/3 and runs through 9,4.


\bf (\stackrel{x_1}{9}~,~\stackrel{y_1}{4})~\hspace{10em}slope =  m\implies -\cfrac{2}{3}\\\\\\\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-4=-\cfrac{2}{3}(x-9)\\\\\\y-4=-\cfrac{2}{3}x+6\implies y=-\cfrac{2}{3}x+10
