Can you solve this math puzzle?
Solve for x and y given the following equations:
2x + 3y = 13
4x – y = 5
Think you know the answer?
To see the answer to the math puzzle, click to expand the accordion below.
x = 2 and y = 3
First, solve the second equation for y. In this case, y = 4x – 5
Next, substitute your new value for y into the first equation. In this case, 2x + 3(4x – 5) = 13
Then solve the remaining equation for x.
2x + 12 – 15 = 13
14x – 15 = 13
14x = 28
x = 2
Now substitute 2 for x into the original equation to solve for y:
y = 4(2) – 5
y = 8 – 5
y = 3
