Question

13=5+4x equals what?????????

Answer 1

The equation 13 = 5 + 4x can be solved for x. By subtracting 5 from both sides, we get:

13 - 5 = 5 + 4x - 5

This simplifies to:

8 = 4x

And finally, by dividing both sides by 4, we find that:

x = 2.

Answer 2

x = 2

Explanation:

To solve an equation, it's important to isolate the variable.

Properties of Equality

The properties of equality, often shortened to PoE, explain how equations can be manipulated while remaining true. For this question, it's important to know 2 of the PoEs. First, the subtraction property of equality states that if a number is subtracted from both sides, then the equation is still true. To reword this:

• if a = b, then a - c = b - c.

Similarly, the division property of equality states that if a number is divided from both sides, then the equation is still true. Once again to reword this:

• if a = b, then a/c = b/c.

Solving for x

We must use these properties of equality to isolate x. Firstly, subtract 5 from both sides.

• 8 = 4x

Then, divide both sides by 4.

• 2 = x

So, in the equation above, x equals 2.
