51 + 2z + 8z = 23
Collect 'like terms'
51 + 10z = 23
Subtract '51' from both sides
10z = 23 - 51 = -28
z = -28 /10
z = - 2.8
NB However, you have NOT indicated the mathematical signs !!!!!

How do you solve 2z plus 1-3 equals z-2?
To solve the equation (2z + 1 - 3 = z - 2), first simplify the left side: (2z - 2 = z - 2). Next, subtract (z) from both sides to get (2z - z - 2 = -2), which simplifies to (z - 2 = -2). Finally, add 2 to both sides to find (z = 0).

Solve system of equation using Gauss Jordan form- When I try to solve these I find that the matrix is singular. Does that mean no solution x plus 2y-3z equals 1 y-2z equals 2 2y-4z equals 4?
The matrix is singular because the last equation is the same as the second equation (simply multiplying every term in an equation by the same number (in this case, 2) does not produce an equation with new information). for example 1) 3x=3y 2) 2x=2y has no useful solution beyond the information from 1) that x=y You would get a singular matrix for this. The Gauss-Jordan method will not solve equations which cannot be solved by the old "elimination method".
