To solve problems like this you can either graph or solve mathematically. To do the ladder we need to solve for one variable at a time. So lets cancel one variable out.
Multiply equation 1 by 2
This will give 4x-2y=14
Now we can get rid of y by subtracting 2 from 1
This will give x=9
Plug back in to either equation, i will use equation 2
3(9)-2y=5 simplify
-2y=-22 solve
Y=11
So this is basically a ratio and the form I use to solve these is
Is. = %
Of. 100
So we're looking for 5% of the 350,000 which will be x
X. = 5
350000. 100
Cross multiply
100x=1750000
Divide by 100
X=17500
Am not sure but i think it would be A

➷ When values with exponents are divided, you should subtract the exponents.
7 - 6 = 1
Your answer should be b^1, which can also be written as just 'b'
