Solving two step equations?
5-7m+9m=11
What are the five steps for solving equations?
Step 1 :Do Add-opp(algebraic definition of subtraction)if possible;if your problem has a minus sign Step 2: Combine like terms. Step 3 :Take the opposite of x(the unknown number) Step 4: Do the same to the other side; whatever you do on one side, you must do to the other Step 5 : Check your answer! :D GOOD LUCK ON THIS!

How do you sulve x over 5 equals 3x minus 4 over 7?
x / 5 = (3x - 4) / 7 When solving equations with one rational expression on both sides, cross multiply. 5(3x - 4) = 7x 15x - 20 = 7x 8x - 20 = 0 8x = 20 x = 5 / 2
What are the points of intersection between the equations of 3x -5y equals 16 and xy equals 7?
If 3x -5y = 16 and xy = 7 then by combining both equations into a single quadratic equation and solving it then the points of intersection are at (-5/3, -21/5) and (7, 1)
What 2 numbers when multiplied equal 20 and when added equal 7?
Let's denote the two numbers as x and y. We can set up a system of equations based on the given information: xy = 20 and x + y = 7. By solving these equations simultaneously, we can find that the two numbers are 5 and 4. This is because 5 * 4 = 20 and 5 + 4 = 9, not 7.
