Question

4x+5=3 find the value of 2x​

Answer 1

Answer:

3x(4x−5)+3=12x

3x(4x−5)+3=12x 2

3x(4x−5)+3=12x 2 −15x+3

3x(4x−5)+3=12x 2 −15x+3x=3 gives the value 12(9)−15×3+3

3x(4x−5)+3=12x 2 −15x+3x=3 gives the value 12(9)−15×3+3 =108−45+3

3x(4x−5)+3=12x 2 −15x+3x=3 gives the value 12(9)−15×3+3 =108−45+3 =66

Answer 2

Step-by-step explanation:

4x+5 = 3

=> 4x = 3-5

=> 4x = -2

=> x = -2/4

=>x = -0.5

2x=> 2× - 0.5 = -1
