Answer 1

Step-by-step explanation:

the sum and difference of the place values of the underlined digits ... slove the following simultaneous equation 4x -3x =0; 2x + 5

Answer 2

Answer:

Solution :-

The given equations are;

4x - 3y = 0 . . . . (1)

2x + 5y = 26 . . . . (2)

Multiply equation (1) by 5 and (2) by 3, we get

20x - 15y = 0 . . . . (3)

6x + 15y = 78 . . . . (4)

Now,

Adding equations (1) and (2), we get,

➜ 20x - 15y + 6x + 15y = 0 + 78

➞ 20x + 6x - 15y + 15y = 78

➞ 26x = 78

➞ x = 78/26

➞ x = 3

Putting the value of x = 3 in equation (2), we get,

➜ 2x + 5y = 26

➞ 2(3) + 5y = 26

➞ 6 + 5y = 26

➞ 5y = 26 - 6

➞ 5y = 20

➞ y = 20/5

➞ y = 4

∴ The value of x = 3, y = 4 is the solution of the system of the given equations.
