Multiply first equation by 5. Then add.

  • myininaya
how about -5 and then after add the equations
myininaya
  • myininaya
5 is fine we would just have to subtract which is fine

It should be subtract. Anyway, once you multiply by 5, it will be clear whether to add or subtract to eliminate x. At least I hope.

please elaborate

\[-10x+30y=-25\] multiplying the top equation by -5 gives us that
myininaya
  • myininaya
now add this to 10x+10y=30

whats the answer
myininaya
  • myininaya
add those equations (-10x+10x)+(30y+10y)=(-25+30)
myininaya
  • myininaya
\[40y=5 => y=\frac{5}{40}\] reduced then plug into one of the equations given and solve for x
myininaya
  • myininaya
sorry i multiplied wrong at first the equation was suppose to be -10x+15y=-25 after multiplying the -5
myininaya
  • myininaya
now add the equations together

i dont remember my teacher explaining it like that.. o.o
myininaya
  • myininaya
\[-10x+15y=-25\] \[10x+10y=30\] ---------------- 0x+25y=5 25y=5 now divide by 25 on both sides then reduce the fraction then plug into one of the equations given and solve for x
