Question

please tell how this can be solve

Answer 1

Simplifying
ax + by = cz

Solving
ax + by = cz

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-1by' to each side of the equation.
ax + by + -1by = -1by + cz

Combine like terms: by + -1by = 0
ax + 0 = -1by + cz
ax = -1by + cz

Divide each side by 'x'.
a = -1bx-1y + cx-1z

Simplifying
a = -1bx-1y + cx-1z
