The product of -1.8 and = -1.8 x ?
3 more than a number = 3 + n
The product of -1.8 and 3 more than a number = -1.8(3 + n)
Is the same as 1/10 = equals (equal sign) 1/10
Full Equation: -1.8(3 + n) = 1/10
Steps to solve:
1. Divide both sides by -1.8 (or - 9/5)
(3 + n) = 1/10 x -5/9
3 + n = -5/90
2. Subtract 3 from both sides
n = -5/90 - 270/90
n = -30 5/9
Hope this helps!
