Question

1 )-x=-4,78+10 2) 2 1/3 - y =4 2/9

Answer 1

1)-х= -4,78+10
-х=5,22
х=-5,22
2)2 1/3 - у=4 2/9
-у=7/3-38/9
-у=21/9-38/9
-у= -17/9
у=17/9

Answer 2

To solve for x, we need to isolate it on one side of the equation.

x = -4.78 + 10

x = 5.22

Therefore, the solution is x = 5.22.

To solve for y, we need to isolate it on one side of the equation. We can start by subtracting 2 1/3 from both sides:

2 1/3 - y = 4 2/9

• y = 4 2/9 - 2 1/3

• y = 38/9 - 7/3

We need a common denominator to subtract the fractions:

• y = (38/9) - (21/9)

• y = 17/9

Finally, we need to multiply both sides by -1 to isolate y:

y = -17/9

Therefore, the solution is y = -17/9.
