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

Add 2y - 4 to each side; 5y - 13 = 0 so y = 2.6

It's a simple linear equation in 'y'.To find the solution:7y - 8 = 2y + 37Subtract 2y from each side of the equation:5y - 8 = 37Add 8 to each side:5y = 45Divide each side by 5:y = 9

5y - 3y = 18 2y = 18 y = 18/2 y = 9

Solving for y: 5y = 9 + 2y 5y - 2y = 9 3y = 9 y = 9/3 = 3

5y + (4 - 2y) = 9 5y + 4 - 2y = 9 3y + 4 = 9 3y = 5 y = 5/3

-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5

x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5

2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6

5y - 3y = 18 2y = 18 y = 18/2 y = 9

3x+2y=9 2y=9-3x y=-1.5x-4.5

4x + 5y = 2 and 7x - 2y = 1 From the first equation, x = (2 - 5y)/4 putting this value of x to the second equation, 7(2 - 5y)/4 - 2y =1 => (14 - 35y)/4 - 2y = 1 =>14 - 35y - 8y = 4 =>14 - 43y = 4 =>43y = 10 => y = 10/43 putting y = 10/43 in x = (2 - 5y)/4 => x =( 86 - 50 )/172 => x = 36/172 => x = 9/43 therefore, x = 9/43 and y = 10/43
