निम्नलिखित बीजीय व्यंजक जोड़ें: 2a - 3b + 4c , -3a + 2b - 5c , 7a - c और 3b + 6c | ...

Add: 3a - 4b + 4c, 2a + 3b - 8c, a - 6b + c

Add: 6a + 8b - 5c, 2b + c - 4a and a - 3b - 2c.

If 2a + 3b + 4c = 35 and 3a + 5b + 7c = 30 , then a + b + c = _____

Simplify: 2a - [3b - {a - (2c - 3b) + 4c - 3 (a - b - 2c)}]

If 2A = 3B = 4C, then A : B : C = ?

If 2A = 3B = 4C then A : B : C = ?

Subtract (2a - 3b + 4c) from the sum of (a + 3b - 4c), (4a - b +9c) and (-2b + 3c -a )

If 2A = 3B and 4B = 5C, then A : C = ?

If a + b + c = 7 // 12 , 3a - 4b + 5c = 3//4 and 7a - 11 b - 13 c = - 7// 12 then what is the value of a + c ?
