a/b = 12
Step-by-step explanation:
2a -5b 1
=
3a+2b 2
We can use cross products to get in the form of a /b
2(2a-5b) = 1(3a+2b)
Distribute
4a -10b=3a+2b
Get the a terms on the left and the b terms on the right
Subtract 3a from each side
4a-3a -10b=3a-3a+2b
a - 10b = 2b
Add 10b to each side
a-10b +10b = 2b+10b
a = 12 b
Divide each side by b
a/b = 12b/b
a/b = 12
