<h2>22</h2>

In this problem, we need to use <u>multiplication</u> and <u>subtraction</u> method to solve it.

_________________________________

x(y) means to <u>multiply</u> x with y

_________________________________

Note that {a = 7} and {b = 6}

First, we need to multiply 4 with {a = 7}, we get:

4(7) = <em>28</em>

<em />

Then, we need to subtract {b = 6} from <em>28</em>, we get:

<em>28</em> – 6 = 22

Finally, this simplifies as:

4(7) – 6 = 22

<em>Hope this helps :)</em>
