Hi.
You want to start off by changing 1 3/4 into an improper fraction.
Now you can easily multiply
5/1*7/4=
You cannot cross cancel, so you just multiply across.
5/1*7/4=35/4
Lastly, you can change it back to a mixed number. 8 3/4
Hope this helps!
150,000 because its 5 or higher add one more 4 or lower just ignore so since its 4 i just lowered it to 0
Good morning
x-3y=-3
x+3y=9
Solve x-3y=-3 for x
Add 3y to both sides
x-3y+3y=-3+3y
x= 3y-3
Substitute 3y-3 for x in x+3y=9
x+3y=9
3y-3+3y=9
Simplify both sides of the equation
6y-3=9
Add 3 to both sides
6y-3+3=9+3
6y=12
Divide both sides by 6
6y/6=12/6
y=2
Substitute 2 for y in x=3y-3
x=3y-3
x= (3)(2)-3
x= 6-3
x= 3
Final answer : X=3, Y=2
I hope that's help !
Have a great Sunday :)
