Why is it necessary to apply inverse operations on both sides of the equals l sign when solving an equations

Mathematics

Take this example (cause it's easy to explain)

10+5x=15x

To solve it we have to minus five on both side. We have to do this because we need to isolate the variable (in this case x) on the one side so we can divide and solve.

You would -5x (inverse from positive 5) from both sides on this because whatever you do to one side you have to do to the others to make it equal. In this case the answer would be x=1 (again cause it's easy lol.)

I hope this helps you!

Wich method can you use yo decide wich of several integers has the greatest value?
serg [7]

Answer:

C

The integer with the greatest value is the one that is farthest to the right hand side of the number line

Step-by-step explanation:

The number line is constructed in a way such that we have a center point of zero with positive values to the right of the number line and negative values to the left of the number line.

Moving deeper right, we have an increase in positivity, with the more positive values rightwards, indicating an increase in the numbers to the right

Moving to the left, we have an increase in negativity, but a decrease in value. The negative numbers closer to zero are more positive and command higher values than the values which are farther from zero.

What these indicates is that the more rightward a number, the greater its value

Evaluate each expression for the given value of the variable.<br> x + 2x - x - 1; x = 2
MaRussiya [10]

x + 2x - x - 1

  • Substitute 2 for x into the expression.

(2) + 2(2) - (2) - 1

  • Multiply 2 * 2 first.

(2) + (4) - (2) - 1

  • Solve from left to right.
  • (2 + 4) - 2 - 1 = 6 - 2 - 1

6 - 2 - 1

  • Solve from left to right.
  • (6 - 2) - 1 = 4 - 1

4 - 1 = 3

<h3>Your answer is 3.</h3>
