Question

3х + 9 = 2х + 5

is it no solutions, all real numbers, or does x equal something?

Answer 1

Topic : Linear equations in one variable

Given :

• 3х + 9 = 2х + 5

Solution :

`\qquad \sf \: { \dashrightarrow 3x + 9 = 2x + 5}`

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

`\qquad \sf \: { \dashrightarrow 3x - 2x = 5 - 9}`

`\qquad \sf \: { \dashrightarrow x = - 4}`

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

Answer 2

x = -4

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)
