The number is 12, if you split it into 3 parts you get 4 so 2/3 of it would be 8. then you just take 20 ans subtract 8 to get 12.
Ok ima try
a x 3 + c x 2 = 14
This is how I learned please don’t roast me if I do it wrong
y=2x+4
-4 -4
-4=2x
-4/2 2x/2
-2=x
Im not 100% sure if this is correct.
Answer:
O No
Explanation:
Given equation: y = 13x + 12
To check if (2, 8) is a solution of the given equation.
Substitute x and y value in equation and check if it is true.

(x, y) = (2, 8)

simplify

This following statement is false and hence (2, 8) is not a solution.
Step-by-step explanation:
4v+6=2(2y+3)
4v+6=4y+6
-4. -4
6=6
