Question

Does someone mind helping me with this question? Thank you!

Answer 1

Answer:

• $\bf -20$

Step-by-step explanation:

$\bf 2(xy-7)$  $\bf when$  $\bf x=-1/y=3$

Substitute with x and y with 3:-

$\bf 2\left(\left(-1\right)(3)-7\right)$

First, Multiply -1 and 3 = -3

$\bf 2(-3-7)$

Subtract  7 from -3 = -10

$\bf 2(-10)$

Multiply 2 and -10 = -20

$\bf -20$
