0.5a-1=4

### 4 Answers | Add Yours

The given equation is:

0.5a-1=4

Adding 1 on both sides, we get

0.5a = 4+1

= 5

Multiplying both sides by 2,

a = 5*2

= 10.

**Therefore, solution to the equation 0.5a-1=4 is a = 10.**

sorry, i didnt understand

i found the answer!

0.5a-1=4

5a/10=4+1

5a/10=5 (we will cross multiply) (as u know that 5 is really 5/1)

5a=50

5a/5=50/5

a=10

0.5a-1=4

0.5a=4-1 = 0.5a=3

a=3/0.5

a=6

0.5a=4+1

0.5a=5

a=5/0.5

a=10
