Hello
First you have to remove your parenthesis and since there is a “+” in front of the parenthesis, the expressions remain the same. So:
9.88+6.7-x = 2,6
Now, you have to add the numbers. So:
16.58-x = 2,6
Next, you have to move the constant (x) to the right and change its sign since it changes side. So:
-x = 2,6-16,58
Now, calculate the difference:
-x = 13,98
And lastly, change the signs on both sides of the equation since - + - equals +. So:
x = 13,98
Hope you found this helpful
Have a good day
