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 \$
