Solutions

Simplifying
3x + -3(2x + -2) = -3

Reorder the terms:
3x + -3(-2 + 2x) = -3
3x + (-2 * -3 + 2x * -3) = -3
3x + (6 + -6x) = -3
<span>Reorder the terms:
6 + 3x + -6x = -3

</span><span>Combine like terms:
3x + -6x = -3x
6 + -3x = -3

</span>Solving
6 + -3x = -3

Solving for variable 'x'.
<span>Move all terms containing x to the left, all other terms to the right.

</span><span>Add '-6' to each side of the equation.
6 + -6 + -3x = -3 + -6

</span><span>Combine like terms: 6 + -6 = 0
0 + -3x = -3 + -6
-3x = -3 + -6

</span><span>Combine like terms: -3 + -6 = -9
-3x = -9</span>
<span>Divide each side by '-3'.
x = 3

Simplifying
x = 3</span>

2. An expression is shown.

Adding parentheses in the component $9\div 3$ of the expression may bring an output of 48.

<h3>Procedure - Application of hierarchy rules in a arithmetic expression</h3>

In this question we should make use of hierarchy rules represented by the use of parentheses. The parentheses oblige to make operations inside it before making it in the rest of the formula.

Now we decide to add parenthesis in the component $9\div 3$ such that the result of the entire expression is 48. We proceed to present the proof:

$2 \times 8 \times (9\div 3)$

$2\times 8 \times 3$

$2\times 24$

$48$

Adding parentheses in the component $9\div 3$ of the expression may bring an output of 48. $\blacksquare$

<h3>Remarks</h3>

The statement presents mistakes and is poorly formatted. Correct form is shown below:

An expression is shown: $2\times 8 \times 9 \div 3$

Using the same expression, add parenthesis so that the value of the expression is 48.

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = 2x - 7

y = -x + 5

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

Substitute in <em>y</em>: 2x - 7 = -x + 5
[Addition Property of Equality] Isolate <em>x</em> terms: 3x - 7 = 5
[Addition Property of Equality] Isolate <em>x</em> term: 3x = 12
[Division Property of Equality] Isolate <em>x</em>: x = 4

<u>Step 3: Solve for </u><em><u>y</u></em>

Define original equation: y = -x + 5
Substitute in <em>x</em>: y = -4 + 5
Add: y = 1
