An equation is a condition where two algebraic expressions are the same. Solving it means that you find all values that you can substitute in place of the variable so that the resulting numbers are equal. The equation 2x + 4 = 10 has a solution of x = 3 because 2*3 + 4 is the same as the number 10 when simplified. x = 5 is not a solution because 2*5 + 4 is equal to 14, not 10. Solving the equation is the process that involves finding out what you can put in place of x that makes both sides of the ...
