Answer 2

It seems like you want to solve the equation (-1.5x + 4.5) / (1 1/7) = 0 for the variable x.

First, let's simplify the equation by converting the mixed number 1 1/7 into an improper fraction:

1 1/7 = 8/7

So, the equation becomes:

(-1.5x + 4.5) / (8/7) = 0

Now, to solve for x, we can multiply both sides of the equation by the reciprocal of 8/7, which is 7/8, to isolate (-1.5x + 4.5) on the left side:

((-1.5x + 4.5) / (8/7)) * (7/8) = 0 * (7/8)

Simplifying the left side:

(-1.5x + 4.5) * (7/8) = 0

Now, we can distribute the 7/8 to both terms inside the parentheses:

(-1.5x * 7/8 + 4.5 * 7/8) = 0

(-10.5x/8 + 31.5/8) = 0

Now, subtract 31.5/8 from both sides:

-10.5x/8 = -31.5/8

To isolate x, multiply both sides by the reciprocal of -10.5/8, which is -8/10.5:

(-8/10.5) * (-10.5x/8) = (-8/10.5) * (-31.5/8)

Simplify the fractions:

(x) = (31.5/8) * (8/10.5)

The 8 in the numerator and denominator cancels out:

x = (31.5/10.5)

Now, simplify the fraction:

x = 3

So, the solution to the equation is x = 3.
