Solution:

Given equation: -8(5 - 3n + 7n) = -40 + 24n - 56n

<u>Simplify both sides:</u>

-8(5 - 3n + 7n) = -40 + 24n - 56n
=> -40 + 24n - 56n = -40 + 24n - 56n

Since both sides are equal, this equation has <u>infinite solutions.</u>

-8(5-3n+7n)= -40+ 24n -56n
-(8•5)-(-8•3n)-(8•7n)=-40+ 24n -56n
-40+ 24n -56n =-40+ 24n -56n

Shkiper50 [21]

The answer is 207 or 2 hundreds 7 ones in unit form or two hundred seven in word form.

<h3>Further explanation</h3>

2 thousands 7 tens are a unit form. The standard form is 2,070.

The key problem is working out the value of 90,000 divide by 10. This is a division operation.

$\boxed{2,070 \div 10 = ?}$

Option-1

Both numbers are divided by 10.

$\boxed{2,070 \div 10 = 207 \div 1}$

The result is

$\boxed{2,070 \div 10 = 207}$

Option-2

Division operations can be written as fractions, like this.

$\boxed{\frac{2,070}{10} = ?}$

The numerator and denominator are both divided by 10, or 'cross out a zero from both'.

$\boxed{\frac{207}{1} = ?}$

The result is

$\boxed{2,070 \div 10 = 207}$

If x is divided by y equals z, then x is equal to y multiplied by z.

$\boxed{If \ x \div y = z \ or \ \frac{x}{y} = z, then \ x= y \times z}$

Let's prove it!

$\boxed{If \ 2,070 \div 10 = 207 \ or \ \frac{2,070}{10} = 270, then \ 2,070 = 10 \times 207}$

This is proven.
