Answer:

x=\dfrac{2}{3}

Step-by-step explanation:

<u>Given equation:</u>

\dfrac{x+1}{2}=\dfrac{7x-3}{2}

Step 1: Multiply both sides by 2.

\implies 2\left(\dfrac{x+1}{2}\right)=2\left(\dfrac{7x-3}{2}\right)

\implies x+1=7x-3

Step 2: Subtract 7x from both sides.

\implies x-7x+1=7x-7x-3

\implies -6x+1=-3

Step 3: Subtract 1 from both sides.

\implies -6x+1-1=-3-1

\implies -6x=-4

Step 4: Divide both sides by -6 and simplify.

\implies \dfrac{-6x}{-6}=\dfrac{-4}{-6}

\implies x=\dfrac{4}{6}=\boxed{\dfrac{2}{3}}

Answer:

\sf x =\dfrac{2}{3}

Explanation:

\sf \rightarrow \dfrac{x+1}{2} = \dfrac{7x-3}{2}

cross multiply

\sf \rightarrow 2(x+1) = 2(7x-3)

divide both sides by 2

\sf \rightarrow x + 1 = 7x-3

isolate variables

\sf \rightarrow x -7x = -3-1

simplify

\sf \rightarrow -6x = -4

divide both sides by -6

\sf \rightarrow \dfrac{-6x}{-6}  = \dfrac{-4}{-6}

simplify

\sf \rightarrow x =\dfrac{2}{3}

Im running out of time Somebody help me out please ​
kobusy [5.1K]

Answer:

3, 4, and 5

Step-by-step explanation:

To put it simply, 3 + 4 + 5 = 12 and the numbers are consecutive, next to each other.

The method:

The three consecutive numbers could be called x, x + 1, and x + 2 and we know that x + x + 1 + x + 2 = 12

This can be simplified to 3x + 3 = 12. Next, subtract 3 from both sides to get 3x = 9. Now, divide both sides by 3 to get x = 3.

This means that the first number is 3 and the other numbers are 4 (3 + 1) and 5 (3 + 2).

Hope this helps!
