12a.
(4a/5) x (3/a) = (12a/5a) = 12/5 = 2.4
3(a + b) + a = 3a + 3b + a = 4a + 3b
If you mean: 4a-3 = 2a+7 then the value of a works out as 5
4a+3 when a=34(3)+312+3=15So you are substituting(replacing) 'a' with the known value of '3'. You then multiply the '4' with the '3' because of the placing of 'a'.
To find the value of (4a - 2b) given (a = 2) and (b = 3), we first substitute the values into the expression. Calculating: [ 4a - 2b = 4(2) - 2(3) = 8 - 6 = 2. ] Thus, the value of (4a - 2b) is 2.
a = -2-4a/3-2 = 8-4a = 8(3-2) times both sides by (3-2)-4a = 24-16-4a = 8-a = 2 divide both sides by 4a = -2 times both sides by -1
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
(4a)2 or 16a2
(4a/5) x (3/a) = (12a/5a) = 12/5 = 2.4
65 times 4a is equal to 260a.

4a x 3
3(a + b) + a = 3a + 3b + a = 4a + 3b
