Answer:
a = -54/7
Explanation:
multiply 7 with the number in brackets
-35 = 5 + 7(a + 2)
-35 = 5 + 7a + 14
then add the numbers without symbols
-35 = 19 + 7a
make a the subject
-7a = 19 + 35
-7a = 54
divide the subject with the same number + the answer
-7a ÷ -7 = 54 ÷ -7
a = -54/7 or -7 5/7
hope this helps :)
