The first mistake made in the steps to solve the equation is; Step 3 is incorrect and should be x = 10/8
<h3>How to solve algebraic equations?</h3>
We are given the algebraic expression;
6x - 1 = -2x + 9
Step 1; By addition property of equality, add 2x to both sides to get;
6x - 1 + 2x = -2x + 2x + 9
8x - 1 = 9
Step 2; By addition property of equality, add 1 to both sides to get;
8x - 1 + 1 = 9 + 1
8x = 10
Step 3; By division property of equality, divide both sides by 8 to get;
8x/8 = 10/8
x = 10/8
Step 4; By simplifying the fraction, we have;
x = 5/4
Step 3 shows 8/10 and as such it is the first mistake.
