In these questions, they're asking you to express x in terms of the other algebra.
So we can simply solve this by imaging them as real numerical values.
rx - sx + y = b
First shift +y to the other side, change it to negative.
rx - sx =b - y
Factories rx - sx by picking out the common factor x.
x ( r - s) = b - y
Shift (r-s) to the other side, and we're done.
x = b - y / r - s
Therefore, the final answer is
Answer:
Is there a picture you can give us? I will try to answer it once you do! :)
The answer to your question is 45
75
Reduction of 12
3 x 4 = 12
Increase of 10
5 x 2 = 10
75 - 12 = 63
63 + 10 = 73
Change = 2 inches (75 - 73)
Well i did this in my notes and i found this
