Question

3x-4y=-13
2x+8y=98

How do I solve this?

Answer 1

(9, 10)

================

Given system:

• 3x - 4y = -13
• 2x + 8y = 98

First, simplify the second equation by dividing all term by 2:

• x + 4y = 49

Next, add up this with the first equation, it will eliminate y:

• 3x + x = - 13 + 49
• 4x = 36
• x = 9

Now, substitute the value of x and solve for y:

• 9 + 4y = 49
• 4y = 40
• y = 10

So, the solution is (9, 10).
