Are you to combine the answer or are they 2 separate equations you need to solve for y?

Since both equal x, just subsitute them
3y-1=x=-2y+9
3y-1=-2y+9
add 2y to both sides
5y-1=9
add 1 to both sides
5y=10
divide both sides by 5
y=2

sub back into any equation
x=3y-1
x=3(2)-1
x=6-1
x=5

x=5
y=2
(5,2)

The sum of three integers is 228. The second integer is 1 more than the first, and the third integer is 2 more than the first. W

MaRussiya [10]

Ok so to start, your unknown numbers will ne represented as x. The equation looks like this: x+x+1+x+2=228. You have your unknown number, the number plus one, and the numner plus two. To find the answer you divide 228 by 3. Those numbers are all equal though,so you play around with them until you get 75+75+1+75+2=228

What is the answer to 2.2=z/57

NeTakaya

It would be 125.4 . Find this by isolation the variable on the right side by using the multiplication property of equality. Multiply both sides by 57 so it would leave you with (125.4 = z). Hope this helps! :)
