Answer: 4
Step by-step explanation: 4 cans for 3 dollars. Since this only costs <em><u>1$ more than</u></em> the possible prices of the <em><u>4 cans</u></em> then that's the answer.
In shorter terms; it's like 1 can cost 2 dollars on the 3 for 4 deal, and 1 can cost 3 dollars on the 9 for 12 deal, find this out by subtracting 9 from 12 and subtracting 3 from 4
Answer:
Simplifying
6x + -3 = 21 + -2x
Reorder the terms:
-3 + 6x = 21 + -2x
Solving
-3 + 6x = 21 + -2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x' to each side of the equation.
-3 + 6x + 2x = 21 + -2x + 2x
Combine like terms: 6x + 2x = 8x
-3 + 8x = 21 + -2x + 2x
Combine like terms: -2x + 2x = 0
-3 + 8x = 21 + 0
-3 + 8x = 21
Add '3' to each side of the equation.
-3 + 3 + 8x = 21 + 3
Combine like terms: -3 + 3 = 0
0 + 8x = 21 + 3
8x = 21 + 3
Combine like terms: 21 + 3 = 24
8x = 24
Divide each side by '8'.
x = 3
Simplifying
x = 3

Answer:
y = x^2+3x-4 y=3x+5
(3, 14)
Step-by-step explanation:
hope this helps and have a nice day!! :)
And also you should try to use Desmos calculator it really helps with these problem/ equations!! you just have to put y = x^2+3x-4 then press enter and on the second one you put y=3x+5 and then it shows you a graph and plus the answer!! :))
