Grade: 7-b Lesson: S2-L6 |
Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
Steps | Problem | Solution |
---|---|---|
1 |
Solve |
\$ x/2 - 4 = (5x)/2 - 14 \$ |
2 |
Move Variable terms to the left side and constant terms to the right side |
\$ (x/2) + ((5x)/2) = -14 + 4 \$ |
3 |
Taking LCM as '\$2\$' |
\$ (x + 5x)/2 = -10/1\$ |
4 |
By using cross multiplication |
\$ x + 5x = -20\$ |
5 |
After Addition |
\$ 6x = -20 \$ |
6 |
Dividing on both sides by '\$6\$' of the equality |
\$ \cancel(6)^1/ \cancel(6)^1 x = -\cancel20^(10)/\cancel6^3 \$ |
7 |
After cancelation |
\$ x = - 10/3 \$ |
8 |
Answer |
D = \$ x = - 10/3 \$ |
