Answer:
Solve for
x
by simplifying both sides of the equation, then isolating the variable.
x
=
−
41
So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

Next, now that we have the value of y, substitute it into either equation to solve for x:

<u>And this is how you get your final answer (5,2).</u>
This is how you would solve the question.
Speed = distance/time
so to work out time you do distance/ speed
234/52= 4.5hours
