Let X be xxx first xxxxxxx and Y xxx second xxxxxxxx
From what you said we xxxx xxx xxxxxxxxx equations:
x x x x xx
x - Y x -13
.
xxxxxx 1.
xx xxxxxxxx xxx second xxxxxxxx xxxx the xxxxx xxxx and xx xxxxx
X + Y - X x (-Y) = - x x (-13) =
x x X x x x Y = -3 x xx =
x x x x Y = 10
x
xx xxxxxx xxxx sides xx xxx xxxxxxxx by 2 and we have:
x x Y xx = 10/2 xx
x = x
.
xx replace xxxx xxxxx xx the xxxxxx equation xxx we have:
X - x = - 13
.
xx add 5 xx both xxxxx of xxx xxxxxxxx xxx xx xxxxx
x x 5 x 5 x -13 x 5 =
X + 0 = - 8 xx
X x x 8
x
The xxxxxxxx is 5 xxx -8.
.
.
xxxxxx 2.
xx xxxx xxx xxxxx xxxxxxxx xxx xx xxxxxxxx x from both sides:
x + x x X = -3 x X xx
x + x = xx - X =
Y = -3 - X
x
xx take xxxx xxxxxxx and xx replace Y xx xxx xxxxxx xxxxxxxxx
X - x = x 13 xx
x - (-3 x X) x xxx xx
