Hey there!
In order to solve this equation for y, you need to use addition, subtraction, and division to combine and simplify the terms. You do this by first eliminating the terms, which you do by completing whatever will make each term equal to zero. Then, you'll repeat this same thing on the other side of the equation, like so:
<span>5y + 3 = 2y – 3x + 5
– 3 – 3
</span>
5y = 2y – 3x + 2
As you can see, I subtracted three from +3 the left side to cancel it out, then repeated that on the right side to the similar term (the constant). Now, just repeat that with your other terms until your equation is equal to y.
5y = 2y – 3x + 2
+ 2y + 2y
<u>7y</u> = <u>–3x + 2</u>
7 7
y = <u>–3x + 2</u>
7
When you can't simplify any more, you have your answer. y will be equal to –3x + 2 over 7.
Hope this helped you out! :-)
<span> y = |x-2|+4
it is a negative 2 because you do the inverse</span>
With the new ratio
3 maple trees for every 11 oak trees
132 oak trees (11*12=132)
3*12 =<span> 36 maple trees
</span><span>36 maple trees plus 132 oak trees = 168 total trees
</span>since your original ratio was 9:5 that means 9/14 of the trees were maple; so set up a proportion to find the number of trees that were maple before the bugs

cross multiply
14x = 1512
x= 108 maple trees before there were bugs
Finally do 108 - 36 (maple trees before, minus, maple trees after)
difference =
78 maple trees
