How do you work out 8x plus 9 equals 6x plus 17?

Answer 1

When you say "work out", we get the uncomfortable feeling that maybe you're not

exactly sure of what you're looking for.

The "solution" to an equation like this is a number. It's the number that 'x' must be

in order to make the whole equation a true statement.

8x + 9 = 6x + 17

Subtract 9 from each side:

8x = 6x + 8

Subtract 6x from each side:

2x = 8

Divide each side by 2:

x = 4
