n/4=n-12
So n=4n-48
Therefore -3n=-48
Finally n=16

Solve the system of equations 3r -4s equals 0 and 2r plus 5s equals 23?
Presumably this is a simultaneous equation in the form of: 3r-4s = 0 2r+5s = 23 Multiply all the terms in the top equation by 2 and in the bottom equation by 3: 6r-8s = 0 6r+15s = 69 Subtract the bottom equation from the top equation: -23s = -69 Divide both sides by -23 to find the value of s remembering that a minus number divided into a minus number is equal to a plus number: s = 3 Substitute the value of s into the original equations to find the value of r: Therefore: r = 4 and s = 3
What is the slope in the equation 9x 5y-50?
Without an equality sign and not knowing the plus or minus value of 5y it is not an equation.

3x plus 4y equals 90 4x-3y equals -5?
This is a simultaneous equation question. 4(3x+4y = 90) 3(4x-3y = -5) Multiply the top equation by 4 and the bottom equation by 3 then subtract the bottom equation from the top equation remembering that in maths a minus from a minus is equal to a plus. 12x+16y = 360 12x-9y = -15 And when subtracted: 0+25y = 375 Divide both sides of the equation by 25 to find the value of y: y = 15 Substitute 15 for y into the original equation to find the value of x: Solution: x = 10 and y = 15
What are the solutions of the quadratic equation 3x2 - x 11?
Without an equality sign and not knowing the plus or minus value of 11 it can't be considered to be an equation.
Given the function y equals minus 3 divided by 4 x square plus 15 what is the value of y when x equal minus 3?

Which expression has a value equal to three eight plus four divide by two minus one times three or eight plus four divided by two minus one times three?
As written, those are the same. For that sentence to equal 3, we need to use parentheses. (8 + 4) divided by 2 minus (1 x 3)
What is the ordered pair of x-2y equals -4 2x-y equals 1?
This is a simultaneous equation question: x-2y = -4 2x-y = 1 Multiply all terms in the top equation by 2: 2x-4y = -8 2x-y = 1 Subtract the bottom equation from the top equation remembering that a minus minus equals a plus: -3y = -9 Divide both sides of the equation by -3 to find the value of y remembering that a minus divided by a minus equals a plus: y = 3 Substitute the value of y into the original equations to find the value of x: Solution: x = 2 and y = 3

What is the equation of 2k equals 5k-30?
2k = 5k-30 Subtract 5k from both sides: -3k = -30 Divide both sides by -3 to find the value of k remembering that a minus divided into a minus becomes a plus: k = 10
