What is 28 - 4y?
if your solving for y, it's y=7. you have to get y alone and to do that you have to divide 4y by 4. now you have y alone. you also have to divinde the other side of the equation(28) by 4...which equals 7
What is an unknown or changable quantity?
It is the variable as for example in the term 4y it is y that is the variable
What is 5x-4y-28?
It is an algebraic expression but if you mean 5x-4y-28 = 0 then it is a straight line equation.
What equation represents a line parallel to the graph of 2x - 4y equals 16?
2x-4y = 16 -4y = -2x+16 y = 1/2x-4 Any equation that has a slope of 1/2 but a different intercept of -4.
What is the slope-intercept form of the linear equation x 4y 12?
If your equation was x + 4y = 12, then: x + 4y = 12 → 4y = -x + 12 ← y = -x/4 + 3 If your equation was x = 4y + 12, then: x = 4y + 12 → 4y + 12 = x → 4y = x - 12 → y = x/4 - 3
How do you get variable alone in 4y equals 3?
4y/4 = 3/4 y = 3/4
How do you isolate a variable in a equation?
There are a few ways to isolate a variable. First, add or subtract anything to get a monomial on one side containing the variable. Then divide by anything that is being multiplied to the variable. Here is an example: xy-4z=2z-4y solving for x xy=(2z+4z)-4y xy=6z-4y x=(6z-4y)/y
What does combine like terms mean in math?
it means to put together the terms that have the same variable. so if you had the equation: 2x+4y+5x it would simplify to 7x+4y because you would combine to the two x-variables.
What it is called when you isolate a variable on one side of an equation?
That is called "solving for a variable". If there is only one variable in the equation, then it is a "solution". For example, 3x + 4y = 13 can be solved for x as 3x = -4y + 13 x = -(4/3)y + 13/3 This is solved for x. Another equation with only one variable: 5z - 6 = 4 5z = 10 z = 2 This is a solution.

What is the variable in the expression 4y plus 9?
4y + 9The variable is Y. The variable is the letter (the unknown amount)
Which line represents 5x plus 4y equals 20?
5x+4y=20 is technically the equation of a line. A more familiar representation of the line is in "y equals" notation. This simply means that the y variable has been isolated (this notation is usually required for graphing calculators). To get the equation in y equals notation, simply isolate the y variable: 5x+4y=20 4y=(-5)x+20 y=((-5)x+20)/4
If you were to solve the following system by substitution what would be the best variable to solve for and from what equation 2x plus 6y equals 9 3x-12y equals 15?
2x + 6y = 93x - 12y = 15Chose the second equation because you can simplify it.3x - 12y = 15 divide by 3 to both sidesx - 4y = 5 add 4y to both sidesx = 4y + 5Replace 4y + 5 for x to the first equation.2x + 6y = 92(4y + 5) + 6y = 98y + 10 + 6y = 914y = -1y = -1/14x = 4y + 5x = 4(-1/14) + 5x = -2/7 + 5x = -2/7 + 35/7x = 33/7
How do you solve 9y-818-4y?
I assume you are solving for y. First you need to form an equation since you don't have an equal sign. The equation would be 9y - 818 - 4y = 0. Next, you have to isolate the unkown number from the known number by adding 818 to both sides of the equation and you would have 9y - 818 - 4y + 818 = 0 + 818, then your equation would read 9y - 4y = 818. Simplify the unknown number by subtracting 4y from 9y which now makes the equation 5y = 818. To find the value of y, divide both sides of the equation by 5. Hence 5y/5 = 818/5. Thus, y = 163.6. To prove the solution, substitute 163.6 for y and solve.
What is an unknown or changable quantity?
It is the variable as for example in the term 4y it is y that is the variable
What is 8=4x+4y?
