Answer:
4/3 =a
Step-by-step explanation:
10 − 3(2a − 1) = 3a + 1
Distribute
10 -6a +3 = 3a+1
Combine like terms
13 -6a = 3a+1
Add 6a to each side
13-6a+6a = 3a+6a +1
13 = 9a+1
Subtract 1 from each side
13-1 = 9a+1-1
12 = 9a
Divide by 9
12/9 = 9a/9
4/3 =a
a = 4/3
10 - 3( 2a - 1 ) = 3a + 1
10 - 3 × 2a -3 × -1 = 3a + 1
10 - 6a + 3 = 3a + 1
10 + 3 - 6a = 3a + 1
13 - 6a = 3a + 1
13 - 6a - 3a = 3a - 3a + 1
13 - 9a = 1
13 - 13 - 9a = 1 - 13
- 9a = - 12
-9a / - 9 = - 12 / - 9
a = 4/3
