Step-by-step explanation:
they are not equivalent
First, set the second equation with y as the isolated variable. To do this, subtract 4 from both sides to get

Now that you know the value of y, put that expression in for y in the first equation to get

Then, simplify by adding the x terms together to get

add 4 on both sides to isolate the x terms to get

then divide 6 from both sides to get

Using that x value, plug it into one of the equations as x to find y ( I will use y=3x-4)

x=1 and y=-1 is the answer

Step-by-step explanation:
Time taken to drive to work = 1 hr
Time taken to drive home = 1 hr
Time taken to drive from home to work and back home again ( IN ONE DAY)
=1 + 1 = 2hrs
So time taken for driving to and from work for 5 days = 2hrs × 5 days = 10 hrs .
