Question

solve:5(x+1) =3(x-2)​

Answer 1

Answer:

Step-by-step explanation:

Expand the brackets, this gives you:

[5x + 5] + [3x - 6]

I just used [ ] to differentiate the two expansions:

so together, your equation is:

5x +5 + 3x - 6

That's,

8x -1

Now since you never put in an = sign, I'm assuming, that you meant 5(x + 1) + 3(x - 2) = 0

If so, then

8x -1 = 0

8x = 1

x = 1/8

However, if you meant to put in the = sign in the middle, so that the equation was supposed to be:

5(x + 1) = 3(x - 2)

Then, we have:

5x + 5 = 3x - 6

Subtracting 3 x from both sides:

=> 2x + 5 = - 6

Subtracting 5 from each side:

=> 2x = -6 - 5

therefore,

2x = -11

x = -11/2 or - 5.5

Good luck on your test!

Answer 2

Step-by-step explanation:

2x+5=3x-6

2x= -11

x= -11/2
