Somewhat, but the rules are a bit different for inequalities. Example. -2X > 4 X < - 2 See, sign changes when dividing by negative coefficient.
This is a pretty simple Algebra 1 question. Compound inequalities are written almost the same way as one-step or multi-step equations, except it has a different sign. Ex: 2+3>5 Hope this works out for you!!!
Simultaneous equations can also be solved by substitution or graphically
Yes.
The inequality sign got lost when writing the question. Anyway, inequalities are basically solved the same way as equations; you transfer everything that has the variable ("x") to one side, and everything else to the other side of the equation - or inequality. The major care you must take is that in an inequality, if you multiply or divide by a negative number, the inequality sign changes direction - for example, a less-than becomes a greater-than.

Mostly true.As with equations, you can add or subtract the same amount to each side of an inequality. You can also multiply or divide by any positive number. The only difference is that if you multiply or divide by a negative number then the direction of the inequality needs to be flipped.For example, if 2x < 8 (ie x < 4), then2x - 8 < 8 - 8or (2x)/4 < 8/4but -3*2x > -3*8

Basically. If the inequality's sign is < or ≤, then you shade the part under the line. If the inequality's sign is > or ≥, then you shade the part over the line.
Even if you keep the decimal, later on you will still have to remove it. It is just an easier way to solve the equation.
Yes.

Yes, they refer to the same thing.
Same way you add equalities. Just find the least common denomenator, and add.
In the same way that you would solve equations because equivalent expressions are in effect equations
