Solutions to EquationsDetermine which of the following are true statements. Check all that applyOw=13 is a solution to ( – 5w – 6) – ( – 4w + 7) = 14Oc= – 3 is a solution to -C – 3 = – 2c – 6x = 12 is a solution to 4(62 + 7) = 2(5z + 98)Oy = – 5 is a solution to 3y + 2 = 4y + 7

Answer 1

You have the following expression:

$\frac{1-3z}{8}=\frac{10-2z}{10}$

In order to determine if z=-5 is a solution to the previous equation, replace z=-5 and verify the equation, just as follow:

$\begin{gathered} \frac{1-3(-5)}{8}=\frac{10-2(-5)}{10} \\ \frac{16}{8}=\frac{20}{10} \\ 2=2 \end{gathered}$

Hence, z=-5 is a solution of the given equation
