Question 217336: Can someone Please help me when this problems?
Solve for x:
1. 3x + 7 = 2x - 5
2. 3 ( x +2) = 27
Solve and graph the solution on the number line:
1. 2 (2 - 3x )< 4 4 ( x + 1)
Perform the indicicated operations:
1. - 9 - ( -2)
2. - 18 -:- 3 - 2
Evaluate :
1. 6x - 3y^2 + 4 when x = 3 and y = - 2

1)
3x+7=2x-5
subtract 7
3x+7-7=2x-5-7
3x=2x-12
subtract 2x
3x-2x=2x-2x-12
x=-12
------------
3rd 1)
-9-(-2)
-9+2=-7
----------------
4th 1)
6x-3y^2+4
6(3)-3(-2)^2+4
18-12+4=10
