Question

Give an example of a variable equation and its solution.

Answer 1

Solve: 3x = 2x + 1


Solution:
3x - 2x = 1

x = 1

By subtracting 2x from
each side, the variables
are all on the same side of the equation.
By combining like terms,
the variable is isolated, and the equation
is simplified and solved.
2. Solve: .4x = .2(.6x) - 4


Solution:
.4x = .12x - 4
.4x - .12x = -4

.28x = -4
.28x/.28 = -4/.28
x = -100/7

Following the order of operations, multiplication
is done first. By subtracting .12x from each
side of the equation, the variables
are all on the same side.
Combine like terms to simplify.
Divide each side by .28 to isolate the variable.
Once the variable is all alone, the answer is found
(it is converted to a fraction because it made
more sense than the decimal answer of -14.28571429 - a
calculator was used for the conversion).
