Question

4r+1.1=6.6r-3.84 I can't if they say if both sign are the same

Answer 1

Solution

For this case we have the following equation given:

4r + 1.1 = 6.6r -3.84

We can subtract 4r in both sides and we got:

1.1 = 2.6r -3.84

Then we can add 3.84 in both sides and we got:

2.6 r = 4.94

And then the value of r we got:

$r=\frac{4.94}{2.6}=1.9$
