Answer:
Step 1 : First, solve one linear equation for y in terms of x .
Step 2 : Then substitute that expression for y in the other linear equation.
Step 3 : Solve this, and you have the x -coordinate of the intersection.
Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.
Step-by-step explanation:
11 15 15/x
Jonah spent the cost of a movie ticket and split the cost of popcorn, so this needs to be represented by a " + ". Jonah just buy one piece tickets, so 11 is tickets price. We know Jonah's costs represented by the expression 11+15/x, "x" on behalf of the number of he and his friends, so 15 is the price of popcprn. 15/x means one person's money for the poopcorn, including Jonah.
On the left side of the equation, we have 3x or 3 * x. But in algebra, we usually just do 3x.
We need to find a value for x that when multiplied by -3 equals to -216.
We can find the value for x by dividing both sides by the coefficient of 3x. Which is 3.
3x / 3 = -216 / 3
x = -72
So, x is equal to -72.
