Question

4x + 5y = 2
2x+3y= 0

does anybody know what x is?

Answer 1

x = 3

y = -2

Explanation:

First, let's solve for y in the top equation:

• 4x + 5y = 2
• 5y = 2 - 4x
• y = 0.4 - 0.8x

Now, plug it in in the second equation:

• 2x + 3(0.4 - 0.8x) = 0
• 2x + 1.2 - 2.4x = 0
• -0.4x = -1.2
• x = 3

We can continue solving for y:

• 2(3) + 3y = 0
• 6 + 3y = 0
• 3y = -6
• y = -2
