In this section of algebra problems ,we study the problems based on quadratic equations, linear equations,matrices, algebraic expressions, sets, functions. All these topics deals thoroughly with all the types of basic and advanced problems in algebra with the statement problems also included.

Given: 2a + 4 = 12

Take -4 on both the sides

2a + 4 - 4 = 12 - 4

2a = 8

Divide by 2 on both the sides

$\frac{2a}{2}$ = $\frac{8}{2}$

a = 4

Take -4 on both the sides

2a + 4 - 4 = 12 - 4

2a = 8

Divide by 2 on both the sides

$\frac{2a}{2}$ = $\frac{8}{2}$

a = 4

Given: 3x - 9 = 27

Take +9 on both the sides

3x - 9 + 9 = 27 + 9

3x = 36

Divide by 3 on both sides

$\frac{3x}{3}$ = $\frac{36}{3}$

x = 12

Take +9 on both the sides

3x - 9 + 9 = 27 + 9

3x = 36

Divide by 3 on both sides

$\frac{3x}{3}$ = $\frac{36}{3}$

x = 12
