Unfortunately, Katie will be $20 short
She has $40
Plus the $38 x 5 she will be earning which is $190
$190+$40 is $230
Looks like Kate needs one more day of hard work to get her bike ; )
        
                    
             
        
        
        
The answer is 14 because a negative number multiplied by another negative number is positive. So (-7)*(-2) is 14.

Hello from MrBillDoesMath!
Answer:
x = 19, y = 36
Discussion:
x + 3 = 22     (*)
2x - y = 2      (**)
Subtract 3 from both sides of (*)
x + 3 -3 = 22 = 3 = 19  =>
x = 19
Substitute x= 19 in (**)
2(19) - y = 2 =>
38 - y = 2 =>           (add y to both sides)
38 -y + y = 2 + y =>
38 = 2 + y  =>         (subtract 2 from both sides)
38 -2 = 2 -2 + y =>
36 = y
