Hey I can help. Do u still need it?
Answer: second option
Step-by-step explanation: To solve this problem, we will need to plug in the value of “x” into our equation to see if it makes sense.
Let’s start by going in order.
-4.9 = -5.7 + 10.6 = 4.9
This will not be the answer because it’s positive 4.9 not negative.
Let’s go on to the last one. If we add positive 0.8 to negative 5.7 we will get the answer of -4.9 and this makes sense.

Answer:</h3>
These steps <em>can</em> be used:
- combine -6 and 4
- combine 15 and -3
- multiply 2 by x and -2
<h3>
Step-by-step explanation:</h3>
The equation could be solved as follows:
2(x -6 +4) = 15 -3 given
2(x -2) = 15 -3 combine -6 and 4
2(x -2) = 12 combine 15 and -3
2x -4 = 12 multiply 2 by x and -2
2x = 16 add 4 to both sides
x = 8 divide both sides by 2
_____
<em>Alternate solution</em>
At step 4, you could have
x -2 = 6 divide both sides by 2
x = 8 add 2 to both sides
