Introduction:
The math practice 4 is the basic concepts involved in mathematics. Here the topic discussed are about the usual terms in algebra like addition, subtraction, multiplication and division. Then it also solves some word problems for easy understandings so that learning math becomes simple and easy for the learners.

Basic concepts:
The math practice 4 involves some basic concepts in mathematics. In this we are going to see about algebra in math practice 4 .They are:
Variables
Expressions
Terms
Polynomials
Equations
Example problems:
Example 1: Solve for x?
79 + 33 = x
Solution:
To find x value
79 + 33 = x
x =112
The answer x is 112
Example 2:
The number decreased by 70 is 12 times its opposite. Find the number.
Solution: First we convert the algebra word problem to a numerical form to get the solution.
The number is decreased by 70 is 12 times its opposite.
Write an equation.
x - 70 = -12x (Equation)
x - 70 + 70 = -12x + 70 (add 70 on both sides we get)
x + 12x = -12x +12x + 70 (add 12x on both sides we get)
11x = 70
x = 6.36
Example 3 : Solve for M?
77 + 3 = M
Solution:
77 + 3 = M
M = 80
The answer M is 80
Example 4: Solve for q?
q + 7 = 49
Solution:
To solve the p value
q = 49 – 7
q = 42
I have recently faced lot of problem while learning free math word problems 5th grade, But thank to online resources of math which helped me to learn myself easily on net.
Example 5: Solve the following system of the linear equations using the method of substitution.
x - y = -6 ,4x+8y = -48
Solution:
Step 1: Rearrange the first equation,
x - y = -6
y = x + 6
Step 2: Substitute this value for y into the second equation;
4x + 8(x + 6) = -48
Step 3: Expand and simplify the equation:
4x + 8x + 48 = -48
12x = -96
x = -8
Step 4: Substitute x back into the one of that original equations;
-8 - y = -6
y = -2
