Answer:

x=9

Step-by-step explanation:

31+39+11x+11=180

Simplify both sides from the equation:

(11x)+(31+39+11)=180 (combine like terms)

11x+81=180

Subtract 81 from both sides

11x+81-81=180-81

You end up with:

11x=99 (Divide both sides by 11)

x=9

Answer:

39+31=70

70+(11x+11)=180

70-70+(11x+11)=180-70

11x+11 = 110

11x+11-11 = 110-11

11x = 99

11x/11 = 99/11

x = 9

GalinKa [24]

The new monthly salary will be $1,457.50.

You received a monthly salary of $1,375.00

Now by economy expansion, causing wages to increase by = 6%

Increment of the salary = 6% of 1,375.00

$= \frac{6}{100} \times 1,375$

$= 0.06 \times 1,375 =\$82.50$

<h3>What is the monthly salary?</h3>

Monthly Salary means Employee's monthly salary, before deductions.
