Y -7.2 = 8 I need this as explanation and in algebraic show

Heyya !

Here's how to do it:-

First write down what's given:-

y -7.2 = 8

Next, we do like this:-

y = 8+ 7.2

We transferred 7.2 to the other side of the ' = ' sign.

When we do so, the sign of the number changes

Here 7.2 was negative first but when we transferred it to the other side, its sign changed to positive.

So,

y = 8 + 7.2

Now, just add it!

8 + 7.2 equals 15.2

6x+4+4x+26+110=180 straight line

10x=180-140

x=40/10=4

<A=4x+26=4×4+26=42
