Question:
Solving system of linear equations and compound inequity
Solve each system by the substitution method. Indicate whether each system is INDEPENDENT, INCONSISTENT or DEPENDENT
1. x+3(y-1)= 11
2(x-y)+8y+28
2. 1/3x-1/6y+1/3
1/6x+1/4y=0
Solve each compound inequity. State the solution set using interval notation and graph it.
3. x <=0 and x+6>3 and 1/4x>3
4. 1/3x>2 and 1/4x>2
5.-1/2x < 6 or 2/3x<4
6. |x /2| - 5 = 1
7. |2x - 8| = 0
