how are the steps to solving an inequality similar to those for solving an equation? how are they different
juin [17]
<h2>Similarities:</h2>
  • With both inequalities and equations, you are solving for a variable by isolating it to one side.
  • A lot of properties that apply to equations apply to inequalities as well (addition property of equality, division property of equality, etc.)
<h2>Differences:</h2>
  • If you divide or multiply by a negative number, you must flip the inequality symbol. Dividing or multiplying by a negative number doesn't affect the equal sign.
  • When graphing the inequality, shaded regions (and the lines themselves if they're solid lines) are a part of the solution. When graphing an equation, only points on that line are solutions.

3(r-1) -2(r+3) =0 anybody know the answer to that ?
agasfer [191]

Answer:

r = 9

Step-by-step explanation:

3(r - 1) - 2(r + 3) = 0

First, use the distributive property.

3r - 3 -2r - 6 = 0

Now, isolate the variable "r" to one side by adding the opposite of the whole numbers to each side so it cancels it out on the left ide and adds it to the right.

3r - 3 -2r - 6 = 0

   +3        +6    +3 +6

3r - 2r = 9

Subtract the r's.

r = 9

Now that we know r = 9, we can plug in 9 into the original (but distributed) expression for every time it uses the variable "r" to check our work.

3r - 3 -2r - 6 = 0

3(9) - 3 - 2(9) - 6 = 0

27 - 3 - 18 - 6 = 0

24 - 24 = 0

0 = 0

So, r = 9 is true.

Hope this helps! If you have any additional questions, please don't hesitate to ask me or your teacher to be sure you master the subject. Stay safe, and please mark brainliest!

Solve the following:<br> 6(2x+3)-3(x-2)=6
REY [17]

The value of x is -2

Step-by-step explanation:

Given that

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

Expand the bracket                    

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

12x + 18 - 3x + 6 = 6

Collect like terms

12x - 3x = 6 - 6 - 18

9x = -18

Divide through by 9

9x / 9 = -18 / 9

x = -2

Therefore, the value of x is -2
