Jada says, "I can tell that -2/3 (x+5)+4(x+5-10/3 (x+5) equals 0 just by looking at it. Is Jada correct? Explain how you know. I know its yes I just don't know how to explain it...Help!

Answer:

Jada is correct.

Step-by-step explanation:

Given equation is as follows,

[tex]-\dfrac{2}{3}\left(x+5\right)+4\left(x+5\right)-\dfrac{10}{3}\left(x+5\right)=0[/tex]

In this case prove that right side of equation is equal to left side of equation.

Now consider left side of the equation,

[tex]-\dfrac{2}{3}\left(x+5\right)+4\left(x+5\right)-\dfrac{10}{3}\left(x+5\right)[/tex]

Factoring out the common term,

[tex]\left(x+5\right)\left(-\dfrac{2}{3}+4-\dfrac{10}{3}\right)[/tex]

Combining the like terms,

[tex]\left(x+5\right)\left(-\dfrac{2}{3}-\dfrac{10}{3}+4\right)[/tex]

Since denominators of first terms are same, so combine the fractions.

[tex]\left(x+5\right)\left(\dfrac{-2-10}{3}+4\right)[/tex]

[tex]\left(x+5\right)\left(\dfrac{-12}{3}+4\right)[/tex]

Divide the number,

[tex]\left(x+5\right)\left(-4+4\right)[/tex]

Subtracting,

[tex]\left(x+5\right)\left(0\right)=0[/tex]

Hence left side of the equation is equal to 0 which is equal to right side of the equation.

Hence Jada saying is correct.
