It's called "elementary algebra".
It looks like this:
2x = 5
Using the axiom "If equals are divided by equals, the quotients are equal.",
divide each side of the equation by 2:
x = 2.5
It seems like you might be missing some context or specific numbers to work with for the equation "equals 30." If you provide a mathematical expression or problem, I can help you solve it or explain how to approach it. Please clarify what you need assistance with!
(five cubed minus five) / (five plus five) equals 12
It means to work out the answer of a given mathematical problem.
here is the mathematical expression, you need an equals sign and something it equals to actually solve for x but I hope this is what you needed or repost with what it equals 4x+4
The first step would be to read the invisible mathematical problems.
Without mathematical notation it's hard to understand the question, but if your question is 5 times s-squared = 25 times s then "s" = "5".
there's no way to solve it
How do you solve 4y plus x equals 8
121 is the answer
With my eyes shut.
Equations allow you to solve mathematical problems.
Rearrange the formula so that the indicated variable is the subject of the mathematical formula.
