Question

1)2a+3a= 3)x+3x= 5)6-2=2)4v-v= 4)7n-4= 6)2a+3b=

Answer 1

1) 2а + 3а = 5а
2) 4v - v = 3v
3) х + 3х = 4х
4) 7n - 4 так и остаётся
5) 6 - 2 = 4
6) 2а + 3b тоже также и остаётся

Answer 2

Let's solve each equation step by step:

1. 2a + 3a = Combining like terms on the left side, we get: 5a =

2. 4v - v = Combining like terms on the left side, we get: 3v =

3. x + 3x = Combining like terms on the left side, we get: 4x =

4. 7n - 4 = To solve for 'n,' we need to isolate it on one side. First, let's move the constant term to the other side of the equation: 7n = 4

Now, to solve for 'n,' we divide both sides by 7: n = 4/7

5. 6 - 2 = Subtracting the numbers on the left side, we get: 4

6. 2a + 3b = The equation cannot be simplified further unless we have specific values for 'a' and 'b.' It remains as it is.

Please note that equation 5) is already solved, and equation 6) cannot be solved without knowing the values of 'a' and 'b.'
