2(y+6)+3y
Multiply the bracket by 2
(2)(y)=2y
(2)(6)=12
2y+12+3y
2y+3y+12 ( combine like terms)
Answer: 5y+12
Answer:
x=17
Step-by-step explanation:
Product means multiply is means equals
2x = 34
Divide each side by2
2x/2 = 34/2
x = 17
Answer:
Adult ticket: $7 Student ticket: $11
Step-by-step explanation:
First, we set up our equations.
x (adult ticket) y(student ticket)
For the first day, 11x + 3y = 110
For the second day, 3x + 6y = 87
Then we solve.
(-2)11x + 3y =110
Equals
-22x - 6y = -220
Add them
-22x - 6y = -220
3x + 6y = 87
This equals
-19x = -133
x = 7
Plug in to find y
3(7) + 6y = 87
21 + 6y = 87
6y = 66
y= 11
Answer:
what i the answerrrr
Step-by-step explanation:
Lets say we have a quadratic equation:
3x^2 + x + 0 = 0
Now, since if we add or subtract 0 from something, the original value stays the same, which means we can write the equation as 3x^2 + x = 0 and ignore the “+0”.
In these kinds of equations, you /can/ use the quadratic formula, but theres a much quicker way. If we factor 3x^2 + x, we get x(3x + 1) = 0. Here, x has two possible values — since the result of the multiplication is 0, that means that either one expression or the other must equal 0. In essence:
If x(3x+1) = 0 then x = 0 or 3x+1 = 0
One of the solutions is that x = 0. Lets find the other.
3x+1=0
3x= -1
x = -1/3
So x1 = 0 and x2 = -1/3. So basically you solve these equations using basic factorization. :)
