Question

Determine the value of x for the following system of equations.

3x + 4y = 70
8x - 3y = 9

Answer 1

If they are 3 waters and 4 sodas you can’t just mix them together so you can’t add but what you can do is divide 3 in both sides to leave x alone divide till you leaves x or y alone

Answer 2

X=6

I used elimination to eliminate the y and solve for x. Hope this helped you!
