°°° Let's see -

Solve for x - BUT, before we do that, I want to look at the right side of the equal sign: I believe the 'x' on the right side '2 x 3 + 2 x 6' is actually a multiplication sign, so we'll replace that with a proper x so that we don't get confused.

°°° Rewrite the equation -

3 (x) + 10 = 2 × 3 + 2 × 6

°°° Simplify both sides of the equation -

3x + 10 = (2) (3) + (2) (6)

°°° Simplify again (Yes, again) -

3x + 10 = 6 + 12

3x + 10 = (6 + 12) (Combine Like Terms)

3x + 10 = 18

°°° Subtract 10 from both sides -

3x + 10 - 10 = 18 - 10

3x = 8

°°° Divide both sides by 3 -

3x / 3 = 8 / 3

x = 8 / 3

°°°FINAL ANSWER°°° -

x = 8 / 3

Graph the line using intercepts: 4x-3y=12

Furkat [3]

First you have to find the intercepts!

To find the y-intercept (I usually do that first), pretend x=0.
Then it becomes:
4(0)-3y=12
Which then becomes:
-3y=12.
Divide both sides, and y = -4.
Then the (x,y) coordinate would become (0, -4).

Next you would find the x-intercept, and pretend y = 0.
Which then becomes:
4x-3(0)=12
3x0 cancels out to become:
4x = 12
And x = 3 because division stuffs.
Then THIS point would then be (3,0).

So then, you would plot (0,-4) and (3,0) on a graph and connect the points! I attached a picture for reference.

hope that helped~
