Question

find the x - value when y = 4 for this equation: x + 3y = 36. what did you just find? x + 3y = 36 x = 24 when y = 4, x must equal to make the equation true.

Explanation:

Step1: Substitute y=4 into equation

$x + 3(4) = 36$

Step2: Simplify the constant term

$x + 12 = 36$

Step3: Isolate x by subtracting 12

$x = 36 - 12$

Step4: Calculate the value of x

$x = 24$

The value found is the x-coordinate of the point on the linear equation $x + 3y = 36$ that corresponds to the y-coordinate of 4, meaning (24, 4) is a solution to the equation.

Answer:

24
