Solve using addition and multiplication principals.
5 + 4x < 21
The solution set is {x/x ??}
Start with the given inequality.
Subtract from both sides.
Combine like terms on the right side.
Divide both sides by to isolate .
Reduce.

Answer:
So the answer is
So the solution set is
Which in interval notation is
Solve the following system of equation
x + 4y = 2 (1)
x = 7 -4y (2)
Start with the given system
Plug in into the first equation. In other words, replace each with . Notice we've eliminated the variables. So we now have a simple equation with one unknown.
Combine like terms on the left side
Subtract 7 from both sides
Combine like terms on the right side
Since this equation is never true for any y value, this means there are no solutions.
