S1: 7x - 4x - 2 = 6 OK
S2: 3x - 2 = 6 OK

Answer: c. Step 3, because a number has been added only to one side of the equation.
Answer:
Y=7+3x, x=-3, y=-2
Step-by-step explanation:
3x-5y=1. Equation 1
3x-y=-7. Equation 2
-y=-7-3x isolate for y in equation 2
y=7+3x multiplied by -1 to get positive y
3x-5(7+3x)=1 substitute y value of equation 2 (7+3x) into equation 1
3x-35-15x=1
-12x=36
x=-3
solve for y.
3x-5y=1
3(-3)-5y=1
-9-5y=1
-5y=10
y=-2
Answer: 3 hours and 20 minutes
Step-by-step explanation:
First , you convert your fraction to a decimal.
6/5 = 1.2
Second , you subtract 4 minus 1.2 to see how much of the work shift does she have left ( since 1.2 hours is what she worked).
4 - 1.2 = 2.8 = 2 hours and 80 minutes (60 minutes is an hour) = 3 hours and 20 minutes
