Answer:

x = -4

Step-by-step explanation:

Given Equation:

  • 3x + 9 = 2x + 5

Question:

  • Whether x has one solution or infinite solutions or no solutions?

Solution:

=> 3x + 9 = 2x + 5

  • (On shifting like terms to one side we get)

=> 3x - 2x = 5 - 9

  • (On subtracting)

=> x = - 4

Result:

Hence, x has only one solution that is, x = -4 (Ans)

Topic : Linear equations in one variable

Given :

  • 3х + 9 = 2х + 5

Solution :

[tex]\qquad \sf \: { \dashrightarrow 3x + 9 = 2x + 5}[/tex]

Transposing variables on one side and constant terms on the other side, we get :

[tex]\qquad \sf \: { \dashrightarrow 3x - 2x = 5 - 9}[/tex]

[tex]\qquad \sf \: { \dashrightarrow x = - 4}[/tex]

  • Hence, the x is equal to something which is (– 4)
