1

Problem

Given that:
\$ 10a + 30 = 7a - 100 \$

2

Hint

Substract both sides on 30

\$ 10a + \cancel(30) - \cancel(30) = 7a - 100 - 30 \$

3

Step

After simplification

\$ 10a = 7a - 130 \$

4

Step

Substract both sides on 7a

\$ 10a - 7a = \cancel(7a) - \cancel(7a) - 130 \$

5

Step

After cancellation

\$3a = -130\$

6

Step

Divide both sides on 3

\$ (\cancel(3)a)/\cancel3 = -130/3\$

7

Step

After cancellation

\$a = -130/3\$
