Answer:
x=(3a+5)/(2a-b)
Step-by-step explanation:
We spread the a to the 2x and -3 first,
2ax -3a= bx+5 5ax
By adding 3a, we pass the -3a over
2ax=bx+5+3aa bx+5+3aa
We'll pass the bx over the bx, then
2ax-bx=5+3aa-bx=5
Now we will party like this on the left side,
5+3a) x(2a-b)=5+3a)
Everything we have to do to find x is to separate both sides by (2a-b)
x=(3a+5)/=(3a+5)/ (2a-b)
Hi!
First, you have to add the addition equation.
(4 + 12) = 4 + 12 = 16
Now, the equation will look like this:
2.3 x 16
Now, you just take this equation like normal:
2.3 x 16 = 36.8
The regular price would be $216
Hope this helps
Using the ratio 4/2 = 2
and 8/4 = 2
so they are similar because 4/2 equals 8/4
Answer:
Step-by-step explanation:
4x - 3y = 18
-4x - 8y = 4
-11y = 22
y = -2
4x + 6 = 18
4x = 12
x = 3
(3, -2)
