Question

3) From the sum of 4 + 3x and 5 - 4x+2x. Subtract the sum of 3x - 5x and -x + 2x+5​

Answer 1

Answer:

Answer is 2x +4.

Step-by-step explanation:

solution is ,

by the sum of the first two equations we get,

4 + 3x

(+) 5 - 4x + 2x is [9+x] equation-1

by the sum of the second two equations we get,

3x - 5x

(+) -x + 2x + 5 is [5-x] equation-2

By subtracting equation-1,2 , we get,

9 + x

(-) 5 - x is (2x + 4).

Final answer is (2x+4)
