Question

What is the soulution of the equation 3(2x+5)=3x+4

Answer 1

x=-
`(11)/(3)`

or

x=-3.666666666666666666666666666666666666666666666

Answer 2

x=-11/3

Explanation:

Given equation is 3(2x+5)=3x+4

Multiplying 3 into the equation we get

6x+15=3x+4

Adding (-3x) and (-15) to both sides of equation

6x+15+(-3x)+(-4)=3x+4+(-3x)+(-15)

Simplifying

6x+15-3x-15=3x+4-3x-15

6x-3x+15-15=3x-3x+4-15

we know that +15-15=0 and 3x-3x=0

3x+0=0-11

3x=-11

dividing by 3 to both sides of equation we get

3x/3=-11/3

x=-11/3 which is the answer.
