3x + 4 - 5 (x + 2) is an equation ; -6 = 2x

Given,

3x + 4 - 5 (x + 2)

We have to find this is whether an expression, equation or inequality.

First we have to solve this:

3x + 4 - 5 (x + 2)

3x + 4 - 5x - 10

- 2x - 6

-6 = 2x

Here, we can identify this is an equation.

What is an equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Compute 33(0.5) - 6(0.5) - 7/2.
lora16 [44]
Hi there! The answer is 10.

33(0.5) - 6(0.5) -  \frac{7}{2}
We can use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.

Since we cannot work inside the parenthesis in this question and since we don't have exponents, we can move on to multiplying.
16.5 - 3 -  \frac{7}{2}

Our next step would be subtracting. To make the process of subtracting some easier, I'll first change the fraction into a decimal.
16.5 - 3 - 3.5

Finally subtract.
13.5 - 3.5 = 10

The answer is 10.
~ Hope this helps you!
