Answer:

A) [tex]5x-1=-6[/tex]

B) [tex]x=-1[/tex]

Step-by-step explanation:

On the left, we have five (positive) Xs and one -1. So, we can represent the left with the expression [tex]5x-1[/tex].

On the right, we have six -1s. So, we can represent the right with the expression [tex]-6[/tex].

A)

Since the balance is balanced, we know that the two expressions are equal to each other. So, we can write the equation:

[tex]5x-1=-6[/tex]

B)

Now, we can solve the equation for x. Add 1 to both sides:

[tex](5x-1)+1=(-6)+1[/tex]

The left will cancel. Add on the right:

[tex]5x=-5[/tex]

Finally, divide both sides by 5:

[tex](5x)/5=(-5)/5[/tex]

The left side will cancel. So, the value of x is:

[tex]x=-1[/tex]

Answer:

A)  5x-1=-6

B) x=-1
