Answer:
[tex] 5x - 1 = -6 [/tex]
[tex] x = -1 [/tex]
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: [tex] 5x - 1 [/tex].
On the other side, we have 6 "-1", which can be represented as: -6.
The equation that can be used to solve x is:
[tex] 5x - 1 = -6 [/tex]
Solve for x. Add 1 to both side
[tex] 5x - 1 + 1 = -6 + 1 [/tex]
[tex] 5x = -5 [/tex]
Divide both sides by 5
[tex] \frac{5x}{5} = \frac{-5}{5} [/tex]
[tex] x = -1 [/tex]
