I don’t know what the answer is I wish I could help

The number is 45.

Step-by-step explanation:

A few ways to do this...but the simplest way I think is to list the two-digit numbers whose tens digit is even and digits add to nine...we have

27

45

63

81

The only one where the ones digit is one more than the tens digit is 45.

Let x= tens digit

Let y = ones digit

Equation 1: x+y = 9

Equation 2: y=x+1

Substitute Equation 2 into Equation 1:

x+ (x+1) = 9

2x + 1 = 9

2x = 8

x = 4

So the tens digit is 4. This means that the ones digit is y =4+1 = 5

1. 11x - 5

2. 3a - 7

3. 4x² - 8

4. x + 20

5. -2x + 5
