Use the distriputive property to simplify each expression.
1. -2 (-3x-5)
2. (3x-7)(3x+5)
add or subtract like terms to simplify the expression.
(3x+2y-4) - (2x-3y+5)
solve the system.
x+3y=10
2x+y=5

The system, x+3y=10
2x+y=5, y is 3 and x=1. to verify, substitute in both equations. For (3x-7)(3x+5) when u multiply u get a quadratic equation. solving d quadratic equation gives u x=7/3 or x=-5/3.

Babe, if you don't understand these basics in Algebra, you are sunk! This is simple stuff. As you progress in this class the problems will become more involved, not harder, just involved using all of the Properties in Alg/
Hint: 1. distriButive Property distribute the -2 individually within the parenthesis
And that's all you'll get from me.

1. 6x+10
2.9x-35
3.x-y+1
ummmm let me see i havent done this in two years
x=10-3y
y=5-2x
(10-3y)+3y=10
10+10
cuz negative and a postive cancel out
