system%286x-5y=-7%2C3x%2B4y=16%29

system%284%286x-5y%29=4%28-7%29%2C+5%283x%2B4y%29=5%2816%29%29
This lets you eliminate terms of y to solve for x.

system%286x-5y=-7%2C-2%283x%2B4y%29=-2%2816%29%29
This lets you eliminate terms of x to solve for y.

by eliminating solve the pairs of simultaneous equation 6x-5y=-7 3x+4y=16
6x - 5y = - 7 ------ eq (i)

3x + 4y = 16 ------- eq (ii)

You only need to CHANGE 1 equation to solve by ELIMINATION, and that's equation (ii)

- 6x - 8y = - 32 --------- Multiplying eq (ii) by - 2 ------ eq (iii)

- 13y = - 39 ------- Adding eqs (iii) & (i)

y = highlight_green%28matrix%281%2C3%2C+%28-+39%29%2F%28-+13%29%2C+or%2C+3%29%29

Now, just substitute 3 for y in any of the 2 original equations and solve for x

It's as simple as that....nothing CONFUSING, nothing COMPLEX!!!
