The answer is

Step-by-step explanation:

use system of equations and substitution.

to solve this equation, one variable needs to be cancelled out to solve for the other.

$-5y+4y=4\\-7y-10x=-10\\$

looking at this problem, we can manipulate -5 and -7 to equal 35 and -35 to get rid of the variable x to solve for y.

$-7(-5y+4x=4)\\5(-7y-10x=-10)\\\\35y-28x=-28\\-35y-50x=-50$

with this, we can cancel out 35x and -35x.

$-28x=-28\\-50x=-50$

manipulate the equation to equal x.

$x=1\\x=1.$

plug 1 for x back into one of the equations to solve for y.

$-5y+4(1)=4\\-5y+4=4\\-5y=0\\y=0$

therefore, (1,0)

hope this helps :)
