WILL GIVE BRAINIEST What major problem did both the Spanish and the Anglos face while trying to establish permanent settlements in Texas? (OC1)

Explanation:

The Spanish Colonial era in Texas began with a system of missions and presidios, designed to spread Christianity and to establish control over the region. The missions were managed by friars from the order of St. ... The missionaries hoped to spread Christianity and the Spanish culture to native groups.

8 - (2a + 7) = a + 40     distribute/multiply - into (2a + 7)

8 - 2a - 7 = a + 40

1 - 2a = a + 40       add 2a on both sides

1 = 3a + 40         subtract 40 on both sides

-39 = 3a       divide 3 on both sides

-13 = a

[proof]

8 - (2a + 7) = a + 40

8 - (2(-13) + 7) = -13 + 40

8 - (-26 + 7) = 27

8 - (-19) = 27

8 + 19 = 27

27 = 27
