I think it’s 0.4285 or 42/85
Answer:
Step-by-step explanation:
Matrix'is determinat:
X1 Y1
X2 Y2
D=(X1*Y2) - (X2*Y1)
D=(3X-4) - (-3*4)
D=0
Determinant of X
I 1 Y1
I 2 Y2
DX=( I 1 *Y2) - ( I 2*Y1)
DX= (14* -4) - (-14*4)
DX=0
Determinant of Y
X1 I 1
X2 I 2
DY= (X1 * I2) - (X2* I1)
DY=(3X-14) - (-3*14)
DY=0
The result of the variables are solved by:
X=DX/D.... Y=DY/D
X=0/0 Y=0/0
X=NaN Y=NaN
Answer:
11g + 19
