Divide each side of the equation by 10 .

whatever the equation is write the equation in words then solve each step in a sentence.

NO!

An "extraneous solution" is not a characteristic of an equation, but has to do with the methods used to solve it. Typically, if you square both sides of the equation, and solve the resulting equation, you might get additional solutions that are not part of the original equation. Just do this, and check each of the solutions, whether it satisfies the original equation. If one of them doesn't, it is an "extraneous" solution introduced by the squaring.

You kind of need to know the problem?

First, subtract 3x from each side of the equation. Then, divide each side of the equation by 7 .

There is no equation in the question, only an expression. An expression cannot be solved.

I have the feeling that you were looking to find a value for each variable in this equation. Unfortunately you can only solve for each variable in terms of the other variables in this equation.

Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18

1). Add ' 3k ' to each side of the equation. 2). Add ' 5 ' to each side. 3). Divide each side by ' 3 ' .

2y6 is an expression not an equation. This is an equation: 2y = 6 To solve that equation you divide each side of the equation by 2: 2y/2= 6/2 y = 3

You're allowed to do that, yes. Whether or not it "solves" any particular equation depends on the equation itself.

By determining whether the numbers of each kind of atoms in the equation are the same on both sides of the equation.

It's not always to 'solve' as it is to 'simplify' EX: 15a + 3b = 45c simplifies to 5a + b = 15c

solve system equation using addition method 3x-y=9 2x+y=6

Here are the steps: -- Write the equation. -- Subtract 7 from each side of the equation. -- Subtract 4x from each side. -- Divide each side by 5.

If 12.89 + h = 36.77,then h = 23.88 after subtracting 12.89 from each side of the equation.

3n=36 Write the equation n=12 Divide each side of the equation by 3 to get the variable alone.

U can subtract 18 from each side of the equation.

Some expressions can't be factorised, and you have to use other methods to solve the equation.

Set up the equation and solve: 13 = 7 + s (next subtract 7 from each side of the equation to solve for s) 6 = s

-- Add 5p to each side of the equation. -- Add 15 to each side of the equation. -- Look at the equation and find the one last step that will give you " p = a number ", which is the solution.

A scientific equation is basically a math equation. Those come in different kinds; each kind needs special techniques for solving. In the simplest case, you have to solve for a single variable; try to transform the equation so that your variable is on the left, and anything else is on the right.
