(25,000+4x)/5=<span>18,600
</span><span>25,000+<span>4x</span></span>=<span>93,000 (multiply both sides by 5)
</span><span>4x</span>=<span>68,000 (subtract 25,000 from both sides)
</span>x=<span>17,000 (divide both sides by 4)
</span>Fitters make $17,000 a year
For this case, we have the following expression:

We simplify the expression:
If we add similar terms, taking into account that different signs are subtracted and the sign of the greater one is placed, we have that 
So, we have to:

Answer:
-3x + x + 5 = -2x + 5
