How would you solve 2x2 plus 4x - 30 equals 0?
By using the quadratic equation formula: x = -5 and x = 3
4x plus 69 equals 30 plus 5x solve for x?
4x + 69 = 30 + 5xSeparate the variables and constants (subtract 4x from each side):69 = 30 + xSubtract 30 from each side (your variable is already a unit) :39 = x
You write 4x plus 4y equals 40?
How do you write 4x plus 4y equals 40 or how do you solve it? You would write it 4x+4y=40 you would solve it for y by subtracting 4x from both sides 4y=40-4x then divide all of that by 4y=40-4x/4 that's if you were graphing i have no idea what you're asking hope that helps if it's not too late.
Solve 6 brackets x-5 brackets equals 4x plus 1?
6x - 30 = 4x + 1 Subtract 4x + 1 from each side giving 2x - 31 = 0 so x = 15.5
How do you find the value of a variable?
you have to solve for the variable for example. 4x + 2y = 8. you would solve for y. so you subtract the 4x and you do the same to both sides and you get 2y = -4x + 8. you then divide everything by 2 to get y by itself and you end up with y = -2x + 4
