Solve the equation 4x-7y equals 12 for y in terms of x then solve it for x in terms of y?
4x - 7y = 12-7y = -4x + 12y = (4/7)x - (12/7)======================4x - 7y = 124x = 7y + 12x = (7/4)x + 3
What is the solution to 10x-7y equals -1 and -2x-7y equals -25?
10x-7y=-110x+1=7y-2x -10x-1=-25-12x-1=-25-12x=-24x=-24/-12x=210(2)-7y=-120-7y=-121=7y21/7=yy=3
10x - 3y plus 2x - 4y?
10x+2x-3y-4y=12x-7y
What are some math parentheses math questions?
You mean like these?: 9 * 2 - (-2 + 9) + 15 / (4.5 + 3) (6x + 7y) * 2 (y - 6x)=(6x*2y)-(6x*12x)+(2y*7y)-(12x*7y)=12xy-72x^2+14y^2-84xy=14y^2-72x^2-72xy
Is the problem 12x plus 7y equals 1600 possible?
Yes, it is.
If 3x equals 7y-2 and 9y equals 4x plus 1 Then what is the value of x and y?
3x = 7y - 2 (subtract 3x and 7y to both sides of the first equation)9y = 4x + 1-7y = -3x - 2 (multiply by 4 each term of both sides of the first equation)9y = 4x + 1 (multiply by 3 each term of both sides of the second equation)-28y = -12x - 827y = 12x + 3 (add both equations)-y = -5 (multiply by -1 both sides)y = 53x = 7y - 2 (substitute 5 for y)3x = 7(5) - 23x = 33 (divide both sides by 3)x = 11Thus, the solution of the given system of the equations is x = 11 and y = 5.
7y-2 equals 14yplus 61?
y=-9 7y-2=14y+61 7y-2-7y=14y+61-7y -2=7y+61 -2-61=7y+61-61 -63=7y -63/7=7y/7 -9=y
What is y times 7y?
Yx7y = 7y2 (squared )
What is the product of (2x-7y)(x y)?
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
How do you factor y squared plus 7y plus 12?
y^2 + 7y + 12 = (y+4)(y+3)
What is the slope for y 12x?
y=12x+0 the slope is 12
What is the y intercept of x plus 7y equals 7?
x + 7y = 7 ⇒ 7y = -x + 7 ⇒ y = -x/7 + 1 ⇒ y intercept is 1.
