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+7=9 equals 2+7=9.

5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3

One equation y equals 9 x equals 14 Don't forget to add it to 23.
Y+7=9 equals 2+7=9.

y = ½ (6y = 3)
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.

It's a simple linear equation in 'y'.If you want to know what value of 'y' makes it true,you can find it like this:23 + Y = 14Subtract 23 from each side of the equation:Y = 14 - 23Y = -9
y = -2/5
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
