Grade: 1300-a Lesson: S1-L1 |
Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Solve the equation \$x + 3(x+2) = 50\$. |
|
2 |
Hint |
Move the variable terms to one side and the numerical terms to the other side. |
|
3 |
Step |
Simplify the equation to make it easier |
x + 3x + 6 = 50 4x = 44 |
4 |
Step |
Finding x value |
\$ x = 44/4 \$ x = 11 |
5 |
Sumup |
Can you summarize what you’ve understood in the above steps? |
|
6 |
Choice.A |
Replacing x with a certain value exposes an incorrect solution, making the equation untrue and unsuitable |
\$ x = 10 \$ |
7 |
Choice.B |
Valid solutions are obtained by substituting a specific value, x, into the equation, confirming its accuracy |
\$x = 11\$ |
8 |
Choice.C |
Replacing x with a certain value exposes an incorrect solution, making the equation untrue and unsuitable |
\$x = 9\$ |
9 |
Choice.D |
Replacing x with a certain value exposes an incorrect solution, making the equation untrue and unsuitable |
\$x = 12\$ |
