Answer:

a=-1

Step-by-step explanation:

First step, simplify both sides.

5a=−(1−4a)

5a=4a+−1

5a=4a−1

Next step, subtract 4a from both sides.

5a−4a=4a−1−4a

a=−1

Answer:

35 - 5a = - (1 - 4a)

remove bracket, change signs as needed

35 - 5a = -1 + 4a

bring variables to one side

35 - 5a + 5a = -1 + 4a + 5a

simplify if needed

35 = -1 + 9a

bring numerical values to the opposite side

35 + 1 = -1 +1 + 9a

simplify if needed

36 = 9a

divide to isolate variable 'a'

36 = 9a

9       9

4 = a

therefore 'a' equals 4
