first you get x alone on both sides. then you divide the number x is next to and you have an answer!!
example
4x-4>8 ::::::problem
4x>12 ::::::: add 4 to both sides. 4+4 and 4+8
x=3 :::::::: divide by 4

Solve the expression 3i 5-2i?
Expressions cannot be solved. Only equations or inequalities may be solved. Also, there is no symbol between 3i and 5.
Why can linear equations and linear inequalities be solved the same way?
Somewhat, but the rules are a bit different for inequalities. Example. -2X > 4 X < - 2 See, sign changes when dividing by negative coefficient.
What is an equation composed of?
An equation is composed of mathematical statements, which can be arranged to result in a series of equations/inequalities which can be solved for each unknown.
Why is it important the linear equations and inequalities?
There are many simple questions in everyday life that can be modelled by linear equations and solved using linear programming.
How do you solve these trinomials x2-x-63 and x2-3-54?
There are no equations nor inequalities in the question only trinomial expressions. Expressions cannot be solved.
How do you solve algebra inequalities?
Algebraic inequalities can be solved in the same fashion as algebraic equations. The goal here, as in algebraic equations, is to isolate the variable. The one thing to remember, however, is that when dividing or multiplying both sides by a negative number, one must switch the inequality sign.
What is the answer of 8c plus 4b 56 - 16b?
There is no answer because the question contains what appear to be two expressions in 2 variables. There are no equations nor inequalities and so there is nothing which can be solved.
What is the relationship between linear algebra and economics?
Many problems in economics can be modelled by a system of linear equations: equalities r inequalities. Such systems are best solved using matrix algebra.
What are the two rules for inequalities which do not occur in equations?
Inequalities are not reflexive. Inequalities are not commutative.
How are word problems with equations different from word problems with expressions?
It may be possible to solve equations. Expressions cannot be solved until they are converted, with additional information, into equations or inequalities which may have solutions.
What is the definition of equivalent inequalities?
The definition of equivalent inequalities: inequalities that have the same set of solutions
What struggles did rosa parks face?
inequalities.
