Hope this helps :)
For this case we have the following equation:

From here, we must clear the value of y.
For this, we follow the following steps:
1) Distributive property:

2) Variable terms on one side of the equation and constant terms on the other side of the equation:

3) Algebraically add the constant terms:

4) Pass the number 20 to divide:

Answer:
The value of y is given by:

$1142.25
Step-by-step explanation:
Gross pay per week = $1500
Social security deducted = 6.2% = $93
Medicare deducted = 1.45% = $21.75
Deductions for combined taxes = 16.2% = $243
Hence total deductions made from the gross salary
= 93+21.75+ 243
= $357.75
Hence, Net pay
= 1500 - 357.75
= $1142.25
