Why did america oppose the axis powers

america opposed the axis powers, because they knew that the united states would be targeted during the war. not only that, but germany (which was an axis power) broke the treaty of versailles, and started developing an army, and started attacking and taking over countries. furthermore, japan, which was allied with germany and italy (who both were axis powers) was attacking china, which was a great ally to the united states.

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
