y=1.2671X-49595
y=x-38633
y=1.2671X-49595
y=x-38633
y=1.2671X-49595①
y=x-38633②
将②代入①中有:
x-38633=1.2761x-49595,
∴1.2761x-x=49595-38633
即0.2761x=10962
∴x≈39703
代入②中有y≈1070
Y=1.2671X-49595①
Y=X-38633②
将②代入①中:
1.2671x-749595=x-38633
即 0.2671x=10962
∴X≈41040.807
将X≈41040.807代入②中
y≈ 2407.807
把方程1代入方程2得
1.2671X-49595=x-38633
x=41040.8087
把x=41040.8087代入2得
y=2407.8087
y=1.2671X-49595
y=x-38633
即
1.2671X-49595=x-38633
0.2671X=49595-38633
X=41040.809
Y=2407.8087
y=1.2671X-49595
y=x-38633
相减后0.2671x-10962=0
x=109620000/2671约为41040.8
y=41040.8-38633=2407.8
y=1.2671X-49595.................1
y=x-38633..........................2
把一式代入二式,得1.2671X-49595=x-38633,整理得0.2671x=10962
则x约等于41041,把x代入二式,得y=2408
