Math Linear Algebra Help

Introduction to math practice test online:
Maths is related to the properties, dimension, and interaction of quantities and sets, using numbers and symbols. Mathematics is used in our daily life. Mathematics consists various topics such as algebra, trigonometric, calculus, geometry, etc. Clear step by step explanation is more useful to know the basic concepts involved in math.Student can get more information through online about math even by staying in their home itself. Now, we are going to see some of the math subject test problems solving online.

Example :
Solve for the variable y: 7y – 23 = 15 + 5y
Solution:
7y – 23 = 15 + 5y
Add 23 on both sides of the equation,find math word problems worksheets help
7y – 23 + 23 = 15 + 5y + 23
7y = 5y + 38
Subtract 5y on both sides of the equation
7y – 5y = 5y + 38 – 5y
2y = 38
Divide by 2 on both sides of the equation,more details Only mathematics

By solving this, we get
y = 19
So, the answer is y = 19.
