simple equation calculator is a free tool and lesson to understand and solve quickly simple equation exercises.
what’s a simple equation?
is a problem with one unique unknown answer that give the solution to a mathematic problem.
example : 2x + 4 = 14 .
the x is the unknown number that we are looking for or the answer.
so if we multiply that number and add the number 4 the sum will be 14.
meaning : 2*x + 4 = 14.
that means, if we do take the 4 from 14, it will give as twice the X (2x) that we are looking for.
so the 4 will be put in the other side of the equation and will be put with the opposit sign ( + to -‘).
so it will be :
2x+4 = 14 ==> 2x=14-4.
time for a simple math : 14-4=10 of course.
here it is : 2x = 10;
but it still need one thing : ) .
yes, of course 2 will be put the other side of the equation with an opposit sign.
2x = 10 ==> x = 10 / 2.
the result is x=5.
lets’s put the result to the test everytime we solve an exercise.
2 * 5 =10 10+4 =14. it’s correct.
concratulations! now you can solve your own math ecercises and your children’s too ;).
