How do you solve the expression 2500x equals 5 please help?
Use the commutative rule in math. If you do something to one side of the equation, you must do the same to the other side. Divide both sides by 2500 to get x = 5/2500, reduce the fraction to get the answer.
How do you solve this equation x over 9 equals 12?
x/9=12 multiply both sides by 9, giving x=108 ____________________________________________________________________ To solve the problem 'x over nine equals twelve', you must first recognize that any number over another number (which includes variables) is a division problem. Thus, all fractions are division problems. You have to multiply by the reciprocal, and multiplication is the opposite of division, and the reciprocal in this case would be 9/1, or just 9. You must apply this to both sides of the equation, so x/9 times 9 is x, and 12 times 9 is 108. Therefore, x =108.
How do you solve an inequality with fractions and variables on both sides?
You solve an inequality the same way you solve an equality. You add and subtract, multiply and divide, both sides by the same value in order to isolate one of the variables. The only extra thing you need to remember is that if you multiply or divide by a negative number, you must reverse the order of the inequality, i.e. less than or equal becomes greater than or equal.
-5b - 12 -2 what is b?
To solve for b, you must form an equation (-5b -12 -2 = 0). Next you must separate the known numbers from the unknown by adding the sum of the knowns to both sides of the equation (-5b = 14). Then divide both sides of the equation by -5 to find the value of b (b = -2.8).
How must is x plus 3 equals -12?
