Solve this simultaneous equation x+2y=11 <br> x-2y=1
lana [24]

Answer:

Equation 1,

x + 2y = 11

Equation 2,

x - 2y = 11

Take equation number 2.

x  -  2y = 11 \\ x = 11  +  2y

Substitute 'x' in Equation number 1.

x + 2y = 11 \\ 11 + 2y + 2y = 11 \\ 11 + 4y = 11 \\ 4y = 11 - 11 \\ 4y = 0 \\ y =  \frac{0}{4}  \\ y = 0

<u>y = 0.</u>

So x,

x = 11 - 2y \\ x = 11 - 2(0) \\ x = 11 - 0 \\ x = 11

<u>x = 11.</u>
