and i do choose best answer!

Answer 1

Um...algebraic expression or equation?

Because this is an expression: x+25

This is an equation: x+25=100

An expression can't be "solved", it just is what it is.

If it's an equation, just use PEMDAS to solve the problem in order!

P-solve for parentheses.

E-solve for exponents (like 3 squared)

M-multiply left to right

D-divide left to right

A-add left to right

S-subtract left to right

So like, here's an equation: 2x-(10+12)=100

1. First, solve what's in the parentheses.

                     2x-22=100

2.Next, divide 2x. But remember what you do to one side, you must do to the other, so divide 100 by 2 also.

                      x-22=50

3. To get x by itself, you have to get rid of -22. So add positive 22 to it to get zero! Repeat on the other side.

                       x=72

X is equal to 72! Done!

I hope I helped!=)

                      

Answer 2

Hm, well I am not sure exactly what you want but I will try.

Example;

1) 3Y+2=6X-5

2) 3Y=6X-7 (Subtracted 2 from -5)

3) Y=2X-7/3 (Divided each side by three)

I hope that's what you needed!

Answer 3

25+y=100. Y=25

Is that the type of algebra you wanted?
