To solve for x, divide by 0.8.
This is a linear equation.
To solve we divide by the coefficient (0.8) in this case.
If you didn't have a calculator, leaving it as a fraction is fine :) .
A none calculator 'cheat type' approach
Takes longer to explain than do the actual calculations. Also demonstrates 'distributive' property of multiplication in step 3.
If it is the decimals that are giving you a problem this is a way round it (for this question).
Multiply both sides by 10
Divide both sides by 8. This changes
Bit of a cheat type approach (not really)
So if we apply three lots of
Next step has to be 'jiggled' about a bit as part of it is
