1

Problem

Given that:
\$ 3/2a - 1/3b, -4/3a - 1/3b, 5/2a + 7/3b \$

2

Step

Add the terms

\$ (3/2a - 1/3b) + (-4/3a - 1/3b) + (5/2a + 7/3b) \$

3

Hint

collecting the like terms

\$ (3/2a-4/3a+5/2a)+(-1/3b-1/3b+7/3b) \$

4

Step

calculating the terms

\$ a(3/2 - 4/3 + 5/2)+b(-1/3 - 1/3 + 7/3)\$

5

Step

Taking LCM

\$a((9-8+15)/6) + b((-1-1+7)/3)\$

6

Step

calculating the terms

\$ a(\cancel16^8/\cancel6^3) + b(5/3)\$

7

Step

After cancellation we get

\$a(8/3)+b(5/3)\$
