Question

Given the equation 3x+4y=20, is the point (4,2) a solution to the equation? Explain and

show you work.

Answer 1

(4, 2) is a solution to the equation

Explanation:

if y = 2 and x = 4 add fill them into the equation

3(4) + 4(2) = 20

12 + 8 = 20

20 = 20

this makes the equation true

So yes, (4, 2) is a solution to the equation.
