Can you please help me can you give me example of set in linear equation and how can i solve it?

solving for y we have this...162 - 18y + 3y = 27...then 162 - 15y = 27...then 162-27 = 15y...then 135 = 15y....then y = 9....

since you already have ur valu for y wch is equal to 9,..you can then substitute this to equation 3 to find x...then we'll have x = 9 -9...x = 0...

so the values for x and y are 0 and 9 respectively.

hope it helped..

linear equation is equation that the highest degree (exponent) is 1 .. or walang exponent.. example: 3x+7
