a) 6x - 5y = 10x + 7 SOLVING FOR X:

6x-5y=10x+7

−5y=10x+7−6x

−5y=4x+7

−5y−7=4x next divide both sides by four and switch sides

$\frac{-5y-7}{4} =x$

$x=\frac{-5y-7}{4}$

a) 6x - 5y = 10x + 7 SOLVING FOR Y:

6x-5y=10x+7

−5y=10x+7−6x then simplify

−5y=4x+7, now divide both sides by negative five

$y=\frac{4x+7}{5}$

b) -4 +(-3) -(-9)

-4+(-3)-(-9) Remove parentheses and simplify.

−4−3+9=−7+9=2

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)
