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}

Answer:

\frac{10x^2+3}{y^2+4}

Step-by-step explanation:

When adding rational numbers, if the denominator is the same you simply keep the denominator (bottom of fraction) as it is and apply the operation given to the numerator ( top of fraction )

So we have \frac{6x^2+5}{y^2+4} +\frac{4x^2-2}{y^2+4} =\frac{(6x^2+5)+(4x^2-2)}{y^2+4}

==> remove parenthesis and apply signs

\frac{x^2+5+4x^2-2}{y^2+4}

==> simplify numerator by combining like terms

\frac{10x^2+3}{y^2+4}

and we are done!

Note:

like terms are terms with the same variable and exponent

An example of like terms are 6x^7 and 3x^7 as they have x as a variable and a power of 7

The like terms being combined here were (6x² and 4x²) and (5 and -2)
