Answer:

a) x = 13

b) x = 7

Step-by-step explanation:

A) Since they have the same base of 2 so

x + 4 + (-5) = 12

x - 1 = 12

x = 13

b) Since they have the same base of -3 so

8 + x + 4 = 19

x + 12 = 19

x = 7

What is the answer to this?

katrin [286]

Answer:

$\huge\boxed{-28}$

Step-by-step explanation:

We can substitute the given values of $a$ , $b$ , and $c$ to find the value of this expression.

$-4 | a + b - c|$

$-4 | 3 + (-2) - (-6)|$

We know that <em>two negatives make a positive. </em>This means that $-2 - (-6)$ will be the same this as $-2+6$

$-4 | 3 + -2 + 6|$

Adding a negative is the same as subtracting a positive.

$\4 | 3-2+6|\\\\3-2+6 = 7$

$-4 \cdot 7 = -28$

Hope this helped!
