Question

Write equation for the statement: Five times a number "b" increased by 2 equals 9

Answer 1

Step-by-step explanation:

2b + 5 = 9

2b = 9 - 5

2b = 4

4

b = -------

2

b =.2

Answer 2

$\huge\blue{\boxed{\mathcal{Question}}}$

Write equation for the statement 5 times a number b increased by 2 equals 9 .

$\huge\pink{\boxed{\mathcal{Solution}}}$

Let the number be x .

Five times a number = 5x

Increased by 2 = 5x + 2

Equals 9 = 5x + 2 = 9

So the Statement formed is 5x + 2 = 9

• A linear equation is a mathematical statement that has both sides equal that is LHS is equal to RHS and gives a straight line when plotted in a graph .

• Constants are numbers that have a fixed value .

• Variables are the terms whose value is unknown .

• Their value is not fixed while solving linear equations often will at their value as alphabets .

• Generally they are x , y and z .When the number of equations is the same as the number of variables there is likely to be a solution for that .

• Well not guaranteed in all cases

• When an equation has no solution it is called inconsistent .

• When an equation has a solution it is called consistent .

• When each equation gives new information it is called independent equation whereas generally there are dependent equations .
