QuestionSolve the equation 2y=2x202y=2x-20 for a given value of 'x' or 'y'.

Studdy Solution

STEP 1

Assumptions1. The equation is y=x20y=x-20 . We are solving for 'y' in terms of 'x'

STEP 2

First, we need to isolate 'y' on one side of the equation. We can do this by dividing every term in the equation by2.
y=2x202y = \frac{2x-20}{2}

STEP 3

implify the equation by performing the division.
y=x10y = x -10Now, 'y' is expressed in terms of 'x'. To find a specific value of 'y', we can substitute the desired 'x' value into the equation.

STEP 4

For example, if we want to find the value of 'y' when 'x' is, we substitute 'x' with in the equation.
y=10y = -10

STEP 5

Calculate the value of 'y'.
y=510=5y =5 -10 = -5So, when 'x' is5, 'y' is -5.
