The answer is 1.6
You start by putting the numbers together
5x=15-7
this gives 8
so yous tate that 5x=8 and divide 8 by 5 so
x=1.6

Here is the working:
5x = 15 - 7
5x = 8
x = 8/5

Subtract 7 on both sides:
5x=8
Divide 5 on both sides:
x=8/5
Check:
5(8/5)+7=15
8+7=15
15=15
I hope this helps!

5x + 7 = 15
5x - 7 + 7 = 15 - 7
5x=8
x=8/5
x= 1.6
There you go. As you can see it is very straight forward.

subtract 7 from both sides
5x = 8
divide both sides by 5
x=1.6
