That depends on the equation. In general, you'll try to isolate the variable, by using operations (on both sides of the equation) that get rid of anything other than the variable, on the side the variable is on.

It is called solving by elimination.

Yes, it is required to figure out some equations.

4x + 5 = 13. To solve algebraic equations, you need to get the variable by itself on one side of the equation. Start by subtracting 5 from both sides >>> 4x = 8. Then divide both sides by 4 to find what 'x' equals >>> x = 2.

First combine all like terms so that the equation is in the form ax + b = 0 Subtract b from both sides to give ax = -b Divide both sides by a which gives x = -b/a.

x-3=0 so add 3 to both sides to isolate the variable. x-3=0 +3 | +3 ________ x-3+3=o+3 _________ x=3
x represents an unknown variable, usually to be solved in algebraic equations eg) 2x = 10 divide both sides of the equation by 2 to get x = 5

To do b equals 2.4 in two step equations, we need to first isolate the variable b on one side of the equation. To do this, we can undo any operations that have been applied to b. For example, if we had the equation 4b = 9.6, we can divide both sides by 4 to get b = 2.4. Similarly, if we had the equation 4b - 8 = 9.6, we can add 8 to both sides of the equation, then divide both sides by 4 to get b = 2.4. Once we have isolated the variable b on one side of the equation, we can set it equal to 2.4 to solve the equation.
