$x = 2$ $y = 3$
#1 The 2 equation is $-x + 2y = 4$ $y = x + 1$ #2 Substitute one equation into 2nd equation solve for X. $-x + 2y = 4$ $-x + 2\times(x+1) = 4$ $-x + 2x + 2 = 4$ $....... .-2..-2$ $-x + 2x = 2$ $x = 2$ #3 Solve for Y Substitute x into one of the equation. $y = x + 1$ $y = 2 + 1$ $y = 3$ #4 $x = 2$ $y = 3$
