Answer:
-80
Step-by-step explanation:
We have: -6 = 
+ 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.
The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.
Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:
-6 - 4 = + 4 - 4 ⇒ -10 =
Then, multiply by 8 on both sides:
-10 * 8 = * 8 ⇒ x = -80
Thus, x = -80.
Hope this helps!
Answer: -5.8x-2.9
Step-by-step explanation:
Hi, to answer this we will use the distributive property:
The distributive property allows to multiply a sum by multiplying each addend separately and then add the products.
(2x + 1) (3.1 – 6)
(2x [3.1]) +(2x[-6])+ (1 [3.1])+ (1 [-6])
6.2x-12x+3.1-6
-5.8x-2.9
