What is -7y plus x?
x = 7y x/7 = y
What is the slope of the line 6x-7y10?
if: 6x - 7y = 10 then -7y = 10 - 6x y = 6x/7 - 10/7 The slope is now the coefficient of x, which is 6/7.
How do you factor x2-y2 plus 7x plus 7y?
(x - y + 7)(x + y)
What is x when y equals x plus 1 divided by x-7?
-6
If 4x-5y equals 4 and 6x-7y equals 10 what is the value of x?
4x - 5y = 4 & 6x - 7y = 10 This is a pair of simultaneous equations. Re-write as 4x - 5y = 4 6x - 7y = 10 To find the value of 'x; we need to eliminate 'y' To do this multiply the top eq'n by '-7' and the bottom equation by '5' . This brings the coefficients of 'y' to the same value, but one is plus(+) and the other is negative(-). Hence -28x + 35y = -28 30x - 35y = 50 Add the two eq'ns, this will eliminate 'y' 2x = 22 x = 11
6x+7y=20Y=2x?
the solution to the system of equations 6x + 7y = 20 and y = 2x is (x, y) = (1, 2)
What is -7y plus x?
x = 7y x/7 = y
What is the slope of the line 6x-7y10?
if: 6x - 7y = 10 then -7y = 10 - 6x y = 6x/7 - 10/7 The slope is now the coefficient of x, which is 6/7.
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.
How do you factor x2-y2 plus 7x plus 7y?
(x - y + 7)(x + y)
How do you factorise 2xy - 6x plus 7y -21?
2x(y - 3) + 7(y - 3) = (2x + 7)(y - 3)
What is x when y equals x plus 1 divided by x-7?
-6

Factor 21-7y plus 3x-xy?
21-7y+3x-xy7(3-y)+x(3-y)
How would you solve 6xn plus 7y equals -6 -2x-3y equals 2 using addition method?
6x+7y=-6 3(-2x-3y=2) +________ -2y=0 => y=0 Therefore x=-1
What is 3x plus 7y equals -16 -x-y equals 4?
y = -1 and x = -3
What is -6x plus 5y equal1 and 6x plus 4yequal -10?
x= -1 y=-1
