Answer 1

Answer:

-9/5

Step-by-step explanation:

3(x-1) +2 (x+3) +6 = 0

3x-3 +2x +6 +6 = 0

5x +9 = 0

5x= -9

x= -9/5

hope it helps you

Answer 2

Question given :

• 3(x-1) +2 (x+3) +6 =0

Required answer :

= 3(x-1) +2 (x+3) +6 =0

= 3x - 3 + 2x + 6 + 6 = 0

= 5x - 3 + 12 = 0

= 5x + 9 = 0

= 5x = - 9

= x = $\sf\dfrac{-9}{5}$

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 .
