Grade: 7-b Lesson: S2-L7 |
Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
Steps | Problem | Solution |
---|---|---|
1 |
Solve |
\$ 8(3 - x/32)= -(- x - 4) \$ |
2 |
After simplification |
\$ 24 - \cancel8^1x/\cancel(32)^4 = x + 4 \$ |
3 |
After cancelation |
\$ 24 - x/4 = x + 4 \$ |
4 |
Move Variable terms to the right side and constant terms to the left side |
\$ -x/4 - x = 4 + 24 \$ |
5 |
Taking LCM as '\$4\$' |
\$ (-x - 4x)/4 = 28 \$ |
6 |
After simplification |
\$ - (5x)/4 = 28/1 \$ |
7 |
By using cross multiplication |
\$ - 5x = 112 \$ |
8 |
Dividing on both sides by '\$-5\$' of the equality |
\$ \cancel(-5)^1/ \cancel(-5)^1 x = 112/(-5) \$ |
9 |
After cancelation |
\$ x = - 112/5 \$ |
10 |
Answer |
B = \$ x = - 112/5 \$ |
