Step Type Explanation Answer

1

Problem

Given that:
\$ (3(x + 12))/4 = (3(7x - 2))/5 \$

2

Hint

After simplification

\$ (3x + 36)/4 = (21x - 6)/5 \$

3

Step

Multiply both sides on \$'4\times5'\$

\$ (3x + 36)/\cancel(4) \times \cancel(4)\times5 = (21x - 6)/\cancel(5) \times 4\times\cancel(5) \$

4

Step

After cancellation

\$ 5(3x + 36) = 4(21x - 6) \$

5

Step

After simplification

\$ 15x + 180 = 84x - 24 \$

6

Step

Substract both sides on 180

\$ 15x + \cancel(180) - \cancel(180) = 84x - 24 - 180 \$

7

Step

After Cncellation

\$15x = 84x - 204 \$

8

Step

Substract both sides on 84x

\$ 15x - 84x = \cancel(84x) - \cancel(84x) - 204 \$

9

Step

After cancellation

\$ -69x = -204 \$

10

Step

Divide both sides on 69

\$ (-\cancel(69)x)/\cancel(69) = -204/69\$

11

Step

After cancellation

\$ x = 204/69\$
