You have an equation with the variable x.
You want to know what value of x makes the equation true.
The first step is to simplify the left side by distributing on both sets of parentheses.

- (1 + 7x) - 6 (-7 - x) = 36

Distribute the negative sign. It changes every sign inside the parentheses.
Distribute the -6. Multiply each number inside the parentheses by -6.

-1 - 7x + 42 + 6x = 36

Now combine like terms on the left side.

-x + 41 = 36

Subtract 41 from both sides.

-x = -5

Divide both sides by -1.

x = 5

Our solution is x = 5.
We can now check to see if it is correct.

We replace x with 5 in the original equation and see it the statement is true.

- (1 + 7x) - 6 (-7 - x) = 36

- (1 + 7*5) - 6 (-7 - 5) = 36

- (1 + 35) - 6(-12) = 36

-36 - (-72) = 36

-36 + 72 = 36

36 = 36

Since 36 = 36 is a true statement, our solution, x = 5, is correct.

frutty [35]

Answer: x=−2.15

Step-by-step explanation : Alright Let's solve your equation step-by-step.

0.5x−2=1.5x+0.15

Step 1: Subtract 1.5x from both sides.

0.5x−2−1.5x=1.5x+0.15−1.5x

−x−2=0.15

Step 2: Add 2 to both sides.

−x−2+2=0.15+2

−x=2.15

Step 3: Divide both sides by -1.

−x

−1

=

2.15

−1

x=−2.15<em>        hope this helped!- Alex</em><u> </u>
