Help on elementary algebra problems

In this lesson… we are going to study on Elementary Algebra Problems. As we all know algebra is a basic to math and more interesting topic for everyone to learn.

Here we begin the practice of solving algebra problems. Problems include the questions involving algebraic equations and basic operations had to be performed to arrive at the solution. Set of solved problems are as shown below.

Following are the elementary algebra questions

Question:1

Solve the following equation:
3(x-1)=8

Answer:

3(x-1)=8
3x-3=8
3x=8+3
3x=11

X = 11 / 3

Question: Which of the following equations have x=2, y=3 as solution ?
(a) 8x-y = 12 (b) 2x+3y = 10.

Answer: (a) Substitute x=2, y=3 in 8x-y=12
8(2)-3=12
16-3=12

x=2, y=3 is not a solution of 8x-y=12
(b) Substitute x=2, y=3 in 2x+3y=10
2(2)+3(3)=10
4+9=10

x=2, y=3 is not a solution of 2x+3y=10.
