Answer: x=-2 *The answer should be the negative sign.*

Step-by-step explanation:

distributive property: a(b+c)=ab+ac

remove parenthesis

-15x-15*4=-30

15*4=60

-15x-60=-30

add 60 both sides of an equation.

-15x-60+60=-30+60

simplify.

-15x=30

divide by -15 both sides of an equation.

-15x/-15=30/-15

simplify.

30/15=2

x=-2

Hope this helps!

Thanks!

Have a great day!

Answer:

$\frac{55}{14}$

Step-by-step explanation:

First, we convert the mixed numbers into improper fractions: $1\frac{3}{7} =\frac{10}{7}$ , and $2\frac{3}{4}=\frac{11}{4}$ . Now, we multiply the fraction using the multiplication rule, $\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}$ : $\frac{10}{7} \times \frac{11}{4} = \frac{110}{28} = \frac{55}{14}$ .
