Solve y=18(x-2): Finding y When x Equals 2

Question

Find a y when x=2

y=18(x2) y=18(x-2)

Video Solution

Step-by-Step Solution

To solve this problem, we need to substitute x=2 x = 2 into the given expression for y y .

  • Step 1: Write down the expression for y y : y=18(x2) y = 18(x - 2) .
  • Step 2: Substitute x=2 x = 2 into the expression.
  • Step 3: Simplify the expression.

Let's perform these steps:

Step 1: The expression given is y=18(x2) y = 18(x - 2) .

Step 2: Substitute x=2 x = 2 into the expression:
y=18(22) y = 18(2 - 2) .

Step 3: Simplify the expression:
Since 22=0 2 - 2 = 0 , we have y=18×0=0 y = 18 \times 0 = 0 .

Therefore, when x=2 x = 2 , the value of y y is 0 0 .
