Simplify -4 + (-3) + 6

1 answer:

3 0

Start off with: -4 + (-3) + 6

First of all, when there is a, + sign and a - sign next to each other, the - side wins. E.g. 1 +- 3 = 1 - 3

So, apply this to our one:
-4 -3 +6

From there you solve, you can do this using the number line method or whatever you are into:
=-7 + 6
=-1
The answer is -1

What value or values of x satisfy 2x + 5.31 = 4.2?

Softa [21]

Answer: x can equal -3.2 or -7.4.

Step-by-step explanation:

The correct expression is:

2|x+5.3|=4.2

So, we have an absolute value equation, where it can be positive or negative:

Positive

2 (x+5.3)=4.2

2x+10.6 =4.2

2x=4.2-10.6

2x = -6.4

x= -6.4/2

x = -3.2

Negative

2[-(x+5.3)]=4.2

-2x-10.6 =4.2

-2x= 4.2+10.6

-2x= 14.8

x= 14.8/-2

x= -7.4

x can equal -3.2 or -7.4.
