The various Algebra Properties used in this question are as detailed below.

<h3>What is the algebra property in use?</h3>

Line 1. 28 + 16 + 4(6 - 7)

Line 2. 28 + 16 + 24 - 28 ; The algebra Property used here is distributive property because 4 was distributed into the terms in the bracket.

Line 3. 28 + 16 + 24 + (-28)

Line 4. 28 + (-28) + 16 + 24; The algebra property used here is commutative property because changing the order of addends does not change the sum.

Line 5. (28 + -28) + (16 + 24); The algebraic property used here is called Associative Property because changing the grouping of addends does not affect the sum.

Line 6. 0 + 40 ; The addition property of equality was used to achieve this.

Line 7. 40

Solve for u. Enter your answer in the answer box and then click Check Answer.
Lunna [17]

Given that:

G=\frac{d}{1-u}

- we cross multiply as follows:

G\times(1-u)=d

- we divide both sides by G, as follows:

\begin{gathered} \frac{G\times(1-u)}{G}=\frac{d}{G} \\  \end{gathered}1-u=\frac{d}{G}

- Subtract 1 from both sides of the equation:

1-u-1=\frac{d}{G}-1-u=\frac{d}{G}-1

- multiply both sides of the equation by -1, as follows:

-u\times-1=(\frac{d}{G}-1)\times-1u=-\frac{d}{G}+1

Therefore, we have that:

u=1-\frac{d}{G}

or:

u=\frac{G-d}{G}
