Simple,

Solving the linear equation of three variables with MATLAB
[x, y, Z] = solve ('2x + y + Z = 10 ','4x + 6y + 2Z = 30','6x + 3Y + 3Z = 35 ','x, y, Z'). Is there a problem with the equation or the grammar

'2 * x + y + Z = 10' should have a multiplier "*"

Solving linear equation with one variable by MATLAB
How to use matlab to solve the following equation
50/(6.5-0.662*ln(t-300))=(350-t)/(3.85-0.662*ln(t-300))

solve('50/(6.5-0.662*ln(t-300))=(350-t)/(3.85-0.662*ln(t-300))','t')

To solve the linear equations of three variables
(1)
x+2y+3z=11
x-y+4z=10
x+3y+2z=2
(2)
x:y=3:5
y:z=5:6
x+y+2z=40
(3)
x+y-z=2
y+z-x=4
z+x-y=6
thank you!

(1) X + 2Y + 3Z = 11 (1) X-Y + 4Z = 10 (2) x + 3Y + 2Z = 2 (3) (1) - (2), 3y-z = 1, (4) (3) - (2), 4y-2z = - 8, that is, 2y-z = - 4, (5) (4) - (5), y = 5, generation z = 14, x = - 39, so x = - 39y = 5, z = 14 (2) x: y = 3:5 (1) y: z = 5:6 (2) x + y + 2Z = 40 (3) from (1), x = (3 / 5) y, from (2)
