Question

7+5y=-13 solve for y

Answer 1

Answer:

5y= -13-7

5y=-20

5y = -20

5 = 5

y = -4

Answer 2

$\large\displaystyle\begin{gathered}\sf 7+5y=-13 \end{gathered}$

Subtract 7 from both sides.

$\large\displaystyle\begin{gathered}\sf 5y=-13-7 \end{gathered}$

Subtract 7 from −13 to get −20.

$\large\displaystyle\begin{gathered}\sf 5y=-20 \end{gathered}$

Divide both sides by 5.

$\large\displaystyle\begin{gathered}\sf y=\frac{-20}{5} \end{gathered}$

Divide −20 by 5 to get −4.

$\boxed{\large\displaystyle\begin{gathered}\sf y=-4 \end{gathered} }\large\displaystyle\begin{gathered}\sf \ \ \to \ \ \ Answer \end{gathered}$

Verification

We let y = -4.

$\large\displaystyle\begin{gathered}\sf \bf{7+5\times-4=-13 \ \ \to \ \ [ Multiply] } \end{gathered}$

$\large\displaystyle\begin{gathered}\sf \bf{7-20 \ \ \to \ \ [Subtract] } \end{gathered}$

$\large\displaystyle\begin{gathered}\sf \bf{-13=-13 \ \ \to \ \ [ Equality \ holds ]} \end{gathered}$
