Ok, so the set up would be 3x+8 = 5x-40. If you solve for x you can then enter it into the equation and get your answer.
So subtract 3x from 3x and 5x. That leaves you with 8 = 2x-40
Next, you add 40 to both sides leaving you with 48 = 2x
Now divide 2 from x and 48 which give x = 24
Enter the value of x into the equation 3x+8
3(24)+8
80
And because we know it is an acute angle, angle ABC = 80 degrees
The constant would be y=3x
<span>5.8+4.1-12.6+x-8.9=-4.6
We move all terms to the left:
5.8+4.1-12.6+x-8.9-(-4.6)=0
We add all the numbers together, and all the variables
x-7=0
We move all terms containing x to the left, all other terms to the right
x=7</span>
9514 1404 393
Explanation:
Add 2x to both sides
-3x=6
Divide both sides by-3
x=-2
_____
First you want to separate the variable terms and constant terms. Here, that is done by adding the opposite of -2x to both sides.
Then you want to divide by the coefficient of x, so you have the variable by itself. Since the coefficient after the first step is -3, you divide both sides by -3.
2x +6y - 4z is the distributed answer.
