3x - 5 = 10 x = ______
Sphinxa [80]

Answer:

3x - 5 = 10 x

The answer is: x=-\frac{5}{7}

Step-by-step explanation:

3x - 5 = 10x

First, Please, Add 5 to both sides, Which would be:

3x - 5 + 5 = 10x + 5

Second, Please, Simplify your answer, Which would be:

3x = 10x + 5

Third, Please, Subtract 10x from both sides, Which would be:

3x - 5 = 10x = 10x + 5 - 10x

Forth, Please, Simplify your answer, Which would be:

-7x = 5

Fifth, Please, Divide both sides by -7, Which would be:

\frac{-7x}{-7}=\frac{5}{-7}

Last and Finally, Simplify your answer, Which would be:

x=-\frac{5}{7}

I hope I helped :)

Find the size of an angle which is five times its supplement ​
zavuch27 [327]

Two supplementary angles when addd together equal 180.


let one angle = x

The second angle is 5 times that so would be 5x


x + 5x = 180

Simplify:

6x = 180

Divide both sides by 6:

X = 30

One angle is 30, the second angle would be 150


The answer is 150
