Question

If (2, 5) is a solution of the equation 2x + 3y = m, find the value of m​

Answer 1

Answer: m = 19

Work Shown:

2x + 3y = m

m = 2x + 3y

m = 2(2) + 3(5)

m = 4 + 15

m = 19

The idea is to replace x with 2 and y with 5. Then use PEMDAS to simplify. When it comes to ordered pairs, the x coordinate is always listed first.
