how to solve simultaneous equations?

Dear sir/madam,

I need to solve two simultaneous linear equations. How could I do this in matlab? Looking forward to hearing from you soon.

Thanking you, BSD

Question

3x+2y=12
4x+6y=18

Matlab code

A=[3, 2 ; 4, 6];
B=[12; 18];
sol=linsolve(A,B)

Answer 1

[Paulo Silva]

Equations:

1x + 2y = 0
2x + 2y = 0

MATLAB code:

A = [1 2;2 2]
B = [0;0]
X = A\B

Mhhhh!

Answer 2

[Mu-izz Gbadamosi]

(x-(cos(alpha1)*(la*cos(theta1)+R)))^2 + (y-(-(R+la*cos(theta1))*sin(alpha1)))^2 + (z-(-la*sin(theta1)))^2 =lb^2;
(x-(cos(alpha2)*(la*cos(theta2)+R)))^2 + (y-(-(R+la*cos(theta2))*sin(alpha2)))^2 + (z-(-la*sin(theta2)))^2 =lb^2;
(x-(cos(alpha2)*(la*cos(theta3)+R)))^2 + (y-(-(R+la*cos(theta3))*sin(alpha2)))^2 + (z-(-la*sin(theta3)))^2=lb^2;

x1+x2=1

0.718+y2 = 1

x1*P"= 0.718*86.8

x2*P2" = y2* 86.8

A=[3, 2 ; 4, 6];

B=[12; 18];

sol=linsolve(A,B)

Step 1: Express your equations into an Augmented Matrix where each equation represents a row of that matrix (excluding the answers/ the value beyond "=" sign.), assign the matrix to a variable. Let say A.

Step 2: Form a column matrix of the answers/ values beyond the "=" sign. Assign the column matrix to another variable B.

Step 3: Compute the solution by 'linsolve()' function OR sipmly A\B=inverse(A)*B

Solution=linsolve(A,B)
