Question

What is 5x+3y=8x-7y when trying to find x it's Geo math

Answer 1

1. Subtract 5x from both sides.
3y=8x-7y-5x
2. Simplify 8x-7y-5x to 3x-7y
3y=3x-7y
3. Add 7y to both sides
3y+7y=3x
4. Simplify 3y+7y to 10y
10y=3x
5. Divide both sides by 3
10y/3=x
6. Switch sides
x=10y/3

Your answer to your problem is x=10y/3.

Answer 2

Rearrange this equation    5x+3y=8x-7y   so that all x terms are on one side and all y terms are on the other:
                                                              10y
5x+3y=8x-7y   =>   10y = 3x, and x = ----------
                                                                3
