Issolvi (x-y)(400+5y)=4250

$$( x - y ) ( 400 + 5 y ) = 4250$$

Solvi għal x

$$x=\frac{y^{2}+80y+850}{y+80}$$

$$y\neq -80$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika x-y b'400+5y.

$$400x+5xy-400y-5y^{2}=4250$$

Żid 400y maż-żewġ naħat.

$$400x+5xy-5y^{2}=4250+400y$$

Żid 5y^{2} maż-żewġ naħat.

$$400x+5xy=4250+400y+5y^{2}$$

Ikkombina t-termini kollha li fihom x.

$$\left(400+5y\right)x=4250+400y+5y^{2}$$

L-ekwazzjoni hija f'forma standard.

$$\left(5y+400\right)x=5y^{2}+400y+4250$$

Iddividi ż-żewġ naħat b'400+5y.

$$\frac{\left(5y+400\right)x}{5y+400}=\frac{5y^{2}+400y+4250}{5y+400}$$

Meta tiddividi b'400+5y titneħħa l-multiplikazzjoni b'400+5y.

$$x=\frac{5y^{2}+400y+4250}{5y+400}$$

Iddividi 4250+400y+5y^{2} b'400+5y.

$$x=\frac{y^{2}+80y+850}{y+80}$$

Solvi għal y (complex solution)

$$y=\frac{-\sqrt{x^{2}+160x+3000}+x-80}{2}$$

$$y=\frac{\sqrt{x^{2}+160x+3000}+x-80}{2}$$

Solvi għal y

$$y=\frac{-\sqrt{x^{2}+160x+3000}+x-80}{2}$$

$$y=\frac{\sqrt{x^{2}+160x+3000}+x-80}{2}\text{, }x\geq 10\sqrt{34}-80\text{ or }x\leq -10\sqrt{34}-80$$
