Question

6z+2=z-4 Solve for z and check solution please

Answer 1

6z + 2 = z - 4
6z + 2 - 2 = z -4 -2
6z = z - 6
6z -z = z - z - 6
5z = -6
z = -6 / 5

Insert it into the top equation.

Answer 2

\[\begin{array}{l} \text{Add }(-z-2)\text{ \to both sides:} \\ 5 z=-6 \\ \text{Divide both sides by }5: \\ z=-\frac{6}{5} \\\end{array}\]
