The answer is: x = 10, y = 2
Leave a thanks because your welcome :)
Work:
x + y = 12
(10) + (2)+ = 12
Correct
x - 2y = 6
(10) - 2(2) = 6
10 - 4 = 6
Correct
PEMDAS
do parentheses first
4 x 10=40
40 x 10=400
1.6+x-3.2=-2+5.6
simplify
-1.6+x=3.6
+1.6 both sides
x=5.2
What lesson are we talking about I will be happy to help.
40 hours at $22.50 is $900. The additional 12 hours at $33.75 is $405.
900+405= 1305 so the secretary’s total wage is $1305
