The value of a is -7
A = 7. 4a + 3 - a = 24 4a - a = 21 3a = 21 a = 7
3a + 4 = 4a - 3 4 = a -3 (subtract 3a from each side) 7 = a (add 3 to both sides) a = 7

3a + 11 = 7a - 13 subtract 3a from each side 3a - 3a + 11 = 7a - 3a - 13 11 = 4a - 13 add 13 to each side 11 + 13 = 4a - 13 + 13 24 = 4a divide each sides integer by 4 24/4 = (4/4)a 6 = a -------------check in original equation 3(6) + 11 = 7(6) - 13 18 + 11 = 42 - 13 29 = 29 ----------------checks out
What is the answers to -7 ( a + b - 5 ) + 8 ( -3a +2b ) + b ( 7 + 3 )
If you mean: 4a-3 = 2a+7 then the value of a works out as 5
