3x + 3 = 5x - 30 -3x +3x 3 = 8x - 30 +30 +30 8x = 33 /8 /8 x = 4 1/8

Improved answer:

Let the unknown number be x:

3x+3 = 5x-30

3x-5x = -30-3

-2x = -33

Divide both sides by -2 to find the value of x remembering that a minus number divided into a minus number is equal to a plus.

x = 16.5

Substituting the value of x into the original equation will give you 52.5 = 52.5

They are both binary operations. The inverse of adding X to a number is the subtraction of X from the result and, conversely, subtracting Y from a number is the inverse of adding Y to the result.

Difference. A sum is the result of adding two numbers, and a difference is the result of subtracting two numbers.

28. Subtracting a negative number gives the same result as adding a positive.

The property of inverse of addition states that for any number a, the inverse of adding a to a number is subtracting a from that number. In other words, if you add a number and its additive inverse, the result is always zero.

Difference. A sum is the result of adding two numbers, and a difference is the result of subtracting two numbers.

Subtracting a negative is like adding a positive; the result will be positive.

The answer 25. Multiplying two negative numbers results in a positive answer. Adding a negative number to that result is the same as subtracting a positive.

Their difference.

Depends. If you are subtracting a bigger number from a smaller number, such as 3 - 5, you will get a negative result, -2. If you are subtracting a smaller number from a bigger number, such as 12 - 3 you will get a positive result, 9.

Because of the definition of addition and subtraction. When looking at a real number line: when you add you move to the left or up, when you add the opposite of a number you move in the opposite direction.
