Ihave an abc broke ya bout ancient rome but can’t find any words for w, x, or y any suggestions?

Wealth

Xulsigiae (a group of Celtic gods linked to the worship of Mars, the Roman god of war.)

Y (originally Rome didn’t have ‘y’ in their vocabulary and over time imported other letters such as ‘y’ ‘k’ ‘z’)

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13
