2x-2y+z=-3,x+3y-2z=1,3x-y-z=2, 2y-y =?
Answers
Explanation:
Answer
(i) Liberals wanted a nation which tolerated all religions. In contrast, radicals wanted a nation in which government was based on the majority of a country's population.
(ii) Liberals did not believe in universal adult franchise. They felt men of property mainly should have the vote. But radicals opposed the privileges of great landowners and wealthy factory owners.
(iii) Liberals did not want the vote for women. On the other hand, many radicals supported women's suffragette movement.

System of Linear Equations entered :
[1] 2x - 2y + z = -3
[2] x + 3y - 2z = 1
[3] 3x - y - z = 2
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -3y + 2z + 1
// Plug this in for variable x in equation [1]
[1] 2•(-3y+2z+1) - 2y + z = -3
[1] - 8y + 5z = -5
// Plug this in for variable x in equation [3]
[3] 3•(-3y+2z+1) - y - z = 2
[3] - 10y + 5z = -1
// Solve equation [3] for the variable z
[3] 5z = 10y - 1
[3] z = 2y - 1/5
// Plug this in for variable z in equation [1]
[1] - 8y + 5•(2y-1/5) = -5
[1] 2y = -4
// Solve equation [1] for the variable y
[1] 2y = - 4
[1] y = - 2
// By now we know this much :
x = -3y+2z+1
y = -2
z = 2y-1/5
// Use the y value to solve for z
z = 2(-2)-1/5 = -21/5
// Use the y and z values to solve for x
x = -3(-2)+2(-21/5)+1 = -7/5
Solution :
{x,y,z} = {-7/5,-2,-21/5}
