Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables. (HSA-REI.C.6)
L: y = 2x + 8 X: y =−3x + −2

X = -X, y= X
XX XXXXXXXXX.
XXXXXXXX: ________(X/2, -4) XXXXXXX
-XX + y = X
y = x -3
x= -X, y= -5
2x + 5y = XX
XX – XX = XX
X= 6, y=8/5
5x + y = X
10x – XX = − XX
X= -1, y=14
XXXX is XXX solution of the system?
Xx + 5y = 14
x + Xy = 16
x=X, y=X
