Answer:
18
Step-by-step explanation:
3x6=6x3=6+6+6=12+6=18
The correct equation to solve for x would be 12x - 19 + 4x + 1 = 180
Answer:
x=-11, y=0. (-11, 0).
Step-by-step explanation:
x-12y=-11
x-y=-11
-------------
x=y+(-11)
x=y-11
y-11-12y=-11
-11y=-11+11
-11y=0
y=0/-11=0
x-0=-11
x=-11+0=-11
To solve the inequality:

Add 1 to the sides of the inequality:

Then

Dividing all the inequality by 5, we have:

Graphically:
Or, in the interval notation(-1, 1/5).
