-13=-13 and -3=-3
solve for m; 4m-12 = 0
m=3
Solve 5x +3 =23
x=4
Solve to check whether x=-3 is a solution
x=-3; x+10 < 6
7 < 6
x=-3 isn't a solution
Simply: 53* 53
53+3=56
Solve to check whether this is a true solution
(3,-2); y<2x
-2 < 6
This is a true statement
Solve for K; -3k = m

3(3 -5x) + 2 = 10
x= -1/15
Solve to check whether x=-2 is a solution
x=-2; 13-x > -8
15 > -8
x=-2 is a true statement
