Answer:
x=2 y=-5
Step-by-step explanation:
7x-y=19
2x-3y=19
Multiply the first equation by -3
-3(7x-y)=19*-3
-21x +3y =-57
Add this to the second equation to eliminate y
-21x +3y =-57
2x-3y=19
-----------------------
-19x = -38
Divide by -19
-19x/-19 = -38/-19
x = 2
Now we need to find y
7x-y = 19
7(2) -y =19
14 -y =19
Subtract 14 from each side
14-14 -y=19-14
-y=5
Multiply by -1
y = -5

Answer: 7
and maybe 5.83
Step-by-step explanation:
If she worked 5 days a week, and worked the same hours of those days, then the answer is 7. You simply divide 35/5 which gives you that answer. And they’ve already given you the answer for Saturday, so yeah.
But you did say she only worked 5 days a week—in 35 hours. And you also said “how many hours did she work on the other days”. If Saturday’s hours was already stated, then are you implying she worked for 6 days instead of 5? Because there’s 7 days a week and if Saturday is unaccounted for, then she worked 6 days. In that case, your answer would be 5.83.
