Solving systems of equations in two variables - Python -


i start learn python , learned variables, input , basic math.

i been asked write mathematical exercise has parameters:

ax+by=c, dx+ey=f

a, b, c, d,e, f - user input , program result , write answear x, y

i did:

number1 = float(input('insert number1: '))  number2 = float(input('insert number2: '))  number3 = float(input('insert number3: '))  number4 = float(input('insert number4: '))  number5 = float(input('insert number:5 '))  number6 = float(input('insert number6: ')) 

i don't how write equation 2 variables

x=number1+2.5*number2-number3 #(it should looked ax+by=c)  y=number5+2.5*number6-number4 

ax+by=c , dx+ey=f ==> x=(-by+ey-f+c)(a-d)

i don't know why can't write variable inside print:

print('the value of x, y is') print((x)) 

well, must think in way solve equation 2 variables using programming language, it's not straightforward if you're not familiar programming.

think steps have take solve manually first , try implement using python, i'll try guiding:

1- find number multiply 1 of equations can "remove" 1 of variables.

2- sum both of equations (forget variables now, work coefficients)

3- after summing both equations , storing "new_coefficient" values , assuming removed x should have like: ((e*step_1_number)+b)*y = f*step_1_number + c

4- previous step you'll able find y value, after it's pretty easy find x value.

i managed using python don't think it's going useful if post code, try work out yourself, luck!
