Andy and Sylvie each incorrectly simplified the expression -3 - 4(2x - 3). Andy wrote -14x + 21 and Sylvie wrote -8 - 6. Explain

vovangra [49]

Answer:

Given the expression -3 - 4(2x- 3) the correct solution is -8x + 9.

Step-by-step explanation:

Andy wrote -14x + 21, so his error was to do de substraction (-3 -4) and then distribute -7(2x-3) = -14x+ 21.

Sylvie wrote -8x -6. Her error was to multiplied -4 only for 2x,

then -3 - 4(2x -3) = -3 -8x -3 = -8x -6.

Answer and Explanation

<h2>The solution of the equation is 20. </h2><h3>( The value of x. )</h3>

__________________________________________________________

The value of x is 20.

We can figure this out by...

__________________________________________________________

$\frac{3x}{5}-x=\frac{x}{15}-\frac{28}{3}$ but what does x equal?

$\frac{3\cdot20}{5}-20$ = $-8$

$\frac{20}{15}-\frac{28}{3}$ = $-8$

Since both are equal to -8, that means $\frac{3\cdot20}{5}-20$ = $\frac{20}{15}-\frac{28}{3}$ .

Which means that...

x = 20
