In general, if you apply the same operation to both sides of an equation, you get an equivalent equation - at least if you do simple things like adding, subtracting, multiplying by a non-zero number, and dividing by some number.

How does writing equivalent equations help you solve a system of equations?
You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.

How do you solve word problems using variables?
Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.

Can you solve for a variable in an equation?
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
Do you answer an equation?
you don't answer an equation, you solve an equation
How do you solve -x equals 1?
in order to solve an equation for x, you must make sure that x is alone, in this case it is not, there is a (-) before it, remember, you have to do the same operation on each side of the equation to make it equivalent to the first equation. if -x=1 x=(-)1 x=-1
What are some ways to solve an equation?
solve it
What equation do you get when you solve 2x plus 3y 12 for y?
If you solve such an equation for "y", you get an equation in the slope-intercept form.
Can you solve the equation 3q 11 8q99?
It is not an equation if it does not have an equals sign. You could simplify it but not solve it.

Can you solve for a variable in an expression or equation?
you can only solve for one in an equation so it can equal something
How do you solve integers?
There is no such thing as "solving integers". You can solve an equation, which means finding all the unknowns in that equation, but you can't solve an integer.
