Add them together then subtract 10 then divide by 8%
Answer:
- 4
Step-by-step explanation:
Using the rule of radicals
×
⇔ 
Simplify
using this rule

= 
=
×
= 3
Then
- 2
+ 2
= - 2(3
) + 2
= - 6
+ 2
= - 4
Just borrow from the 7 and take the 1 to the 2 and that will make it as 12 so then you subtract 12 - 4 and the answer will be 1,180
3+1/x *x = 7/x*x
3x+1 = 7
3x+1-1=7-1
3x=6
3x/3 =6/3
x =2
