Question

Find the value of x. (a) x + 13 - 18​

Answer 1

Step-by-step explanation:

The value of x is 5. Here are the workings below:

x + 13= 18

x+ 18 - 13

x= 5

You find it by shifting the 13 to the right and changing its sign plus to minus. You can find other similar equations the same way as well. Like, for example:

x - 12 = 15

x is found by shifting 12 to right. When you shift it to the right, you must change it to the opposite sign. So, negative becomes positive.

x= 15 + 12

So, x=27
