Question

Use the equation equation y = -3x + 2 to find the missing value.Given the output = -4

Answer 1

Answer:

x=2

Explanation:

We need to find the value of x when y is equal to -4

So, if we replace y by -4 on the initial equation, we get:

y = -3x + 2

-4 = -3x + 2

So, subtracting 2 on both sides of the equation:

-4 - 2 = -3x + 2 - 2

-6 = -3x

Dividing by -3, we get:

$\begin{gathered} \frac{-6}{-3}=\frac{-3x}{-3} \\ 2=x \end{gathered}$

Therefore, the missing value is x = 2
