4x-5y+20 = 0 -5y = -4x-20 y = 4/5x+4 which is now in slope intercept form
what is the solution of x-5y=10 and 2x-10y=20
If: 20x+5y = 15 Then: y = -4x+3
12y - 4 = 7y + 165y = 20y = 4
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
y = -6
x = 0 and y = 4
The Commutative Property of Addition.
-x + 5y = 10 5y= 11 y = 11/5
One linear equation in two variables (x and y) cannot be solved.
5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
This cannot be solved for numerical answers. There must be 2 equations if there are 2 variables.
It is not possible to solve a single linear equation in two variables.
To solve for two unknown variables (x and y) you require two independent equations,
-8 - 5y = 12 - 9y -8 + 4y = 12 4y = 20 y = 20/4 or 5
X = 0 (zero) Y = -1 (neg 1)
If: 3y+8 = 5y-20 Then: 3y-5y = -20-8 So: -2y = -28 And: y = -28/-2 => y = 14
