<em>Algebraic expressions</em> include both <u>alphabet </u>and <u>number</u> so that the value of the <u>alphabet</u> is to be <em>determined</em>. Thus the steps taken by Tyler are correct if x = 22.
ii. Tyler made no mistake.
<em>Algebraic expressions</em> include both <u>alphabet</u> and <u>number</u> so that the <em>value</em> of the <u>alphabet</u> is to be determined. The <u>value</u> of the <u>alphabet</u> in the <em>expression</em> would be determined by applying <em>mathematical operations</em> appropriately.
To solve the <u>question</u> given to Tyler, we have:
= -5
<u>square</u> both <em>sides</em> of the equation to have;
(x + 3) =
x + 3 = 25
collect <em>like terms</em> to get;
x = 25 - 3
= 22
x = 22
1. Thus the equation is true if x = 22.
2. <u>Tyler</u> did not make any <u>mistake</u> in solving for x.
