3x+10y=13<br> 4(-2y+x)-9x=13
mart [117]

Answer:

x=-9

y=4

Step-by-step explanation:

3x+10y=13 ← Equation 1

4(-2y+x)-9x=13\\

By simplifying the above equation we get,

-8y+=4x-9x=13 (Simplifying the brackets)

-8y-5x=13 (By subtracting -9x from +4x) ← Equation 2

Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.

Equation 1 multiplied by 5 will give,

15x+50y=65

Equation 2 multiplied by 3 will give,

-24y-15x=39

Add those together,

15x+50y-24y-15x=65+39

26y=104 (After simplifying x values)

Therefor y=4

By substituting y=4 to Equation 1 we get,

3x+10*4=133x+40=13\\3x=-27\\x=-9

Therefor we can say,

x=-9

y=4
