#### Answer

x = 2
y = -1

#### Work Step by Step

3x - 4y = 10
y = x - 3
Substitude y = x - 3 to the first equation
3x - 4 ( x - 3 ) = 10
3x - 4x + 12 = 10 use the distributive property
- x + 12 = 10 simpify
-x +12 - 12 = 10 - 12
-x = -2 multiply by (-1 )to both sides
x = 2
y = 2 - 3 substitude x for 2 to the second equation
y = -1
