Question

This model represents an equation

Answer 1

Answer:

$5x - 1 = -6$

$x = -1$

Step-by-step explanation:

The model above shows a weigh balance which can be represented by an equation have two sides, of which must be equal to each other.

On the right of the equation, we have 5 "x" and 1 "-", which can be represented as: $5x - 1$.

On the other side, we have 6 "-1", which can be represented as: -6.

The equation that can be used to solve x is:

$5x - 1 = -6$

Solve for x. Add 1 to both side

$5x - 1 + 1 = -6 + 1$

$5x = -5$

Divide both sides by 5

$\frac{5x}{5} = \frac{-5}{5}$

$x = -1$
