2x + y = 5
4x - 2y = 6

Assuming you want to solve for x,

x = 2

Step-by-step explanation:

2x + y = 5

Solve for y

y = 5 - 2x

4x - 2y = 6

Solve for y

y = -3 + 2x

Since both these equations equal y, they must equal each other.

Make an equation for these to equal each other.

Then solve for x

5 - 2x = -3 + 2x

  + 2x        + 2x Add

5 = - 3 + 4x

+ 3  +3 Add

8 = 4x

/4  /4 Divide

2 = x

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
