9x + y = 9 3x + 3y = -12
Citrus2011 [14]

Answer:

x = 13/8

y = -45/8

Step-by-step explanation:

9x + y = 9

3x + 3y = -12

Divide the second equation by 3

x+y = -4

Multiply this by -1

-x -y = 4

Add this to the first equation to eliminate y

9x + y = 9

-x -y = 4

-----------------

8x +0 = 13

Divide by 8

8x/8 = 13/8

x = 13/8

Now find y

x+y = -4

13/8 +y = -4

Subtract 13/8 from each side

13/8 -13/8 +y = -4-13/8

y = -32/8 - 13/8

y = -45/8

Bumek [7]

Lucy's gross pay per week is $393.75.

Lance's tax payment amount is $10983.

Lance's net pay is $41,317.

Lance's every paycheck of two will be around $2179 per month.

<h3>How find the pay?</h3>

1) Lucy earns $15.75 per hour.

Last week she worked 25 hours.

Solution:

Lucy's gross pay per week is $15.75 * 25 hours.

Lucy's gross pay per week = 15.75 * 25  =  $393.75

2) Lance has a yearly salary of $52,300

He pays 21% as taxes.

Solution:

a) Lance tax pay amount = 21/100*52,300 = $10983

b) Lance's net pay =  $52,300 - $10983 =  $41,317

c) Per month salary = $52,300/12 =  $4358

Each paycheck will be 4358/2 = $2179
