|1|{sbBox2-problem} 2+|Solve the equation: 2(3x - 1) = 5(2x + 4) - 3. |2|{sbBox2-hint} 2+|Move the variable terms to one side and the constant terms to the other side. |3|Step:|After making the equation simpler | 6x - 2 = 10x + 20 - 3

6x - 10x = 20 - 3 + 2

⇒ - 4x = 19 |4|Step:|To solve for x, we can divide both sides by - 4 | \$ x = - 19/4 \$ |5|{sbBox2-sumup} |Can you summarize what you’ve understood in the above steps? |audio::https://uat-media.saibook.org/edu/family/counselor/v3/common/lesson/steps/sumup.mp3[width=24px,,float="right"] |6|{sbBox2-choice-a}|Plug in a particular value for x reveals an incorrect solution, making the equation invalid and unsuitable | \$ x = 18/4 \$
|7|{sbBox2-choice-b}|Plug in a particular value for x reveals an incorrect solution, making the equation invalid and unsuitable | \$x = - 18/4\$
|8|{sbBox2-choice-c}|Plug in a particular value for x reveals an incorrect solution, making the equation invalid and unsuitable | \$x = 19/4\$
|9|{sbBox2-choice-d}|Substitute x into the equation to verify its accuracy and obtain valid solutions for the problem | \$x = - 19/4 \$
