Solve Math Problems

Introduction to solve math problems

Solve math problems is very simple. Math is very biggest subject and interesting subject which are very important for our life. Many topics of math problem are there to find and solve according to the problems given. To solve math problems we have different sequence of steps, methods, functions and formulae every thing. Solve math problems includes topics like algebra, arithmetic operations, functions, limits, calculus trigonometry etc. Many other topics are also involved in mathematics that have different models of problems that are to be solved.  Here some of the math problems are solved.

solve math problems


1. Solve 1 0 5 7 x 3

Solution

1 0 5 7
3 x
-----------
3 1 7 1
----------
2. Solve

a) 15 +46 =? – 8

b) 25 – 17 = 4 +? +1

Solution

a) 15 + 46 =? – 8

61 =? – 8

61 + 8 = 69

So the answer is 69

15 + 46 =69 – 8

b)  25 – 17 = 4 +? +1

25 – 17 = 5 +?

8 = 5 +?

8 – 5 =?

So the answer is 3

25 – 17 = 4 +3 +1

3. Solve 3x + 5 = 20

Solution

3 x + 5 = 20

Subtract 5 on both sides

3 x + 5 – 5 = 20 – 5

3x = 15

Divide by 3

x = 3.
