Решить систему уравнений: 3(х+2у)-26=3у-2х 15-(у-3х)=2у+5 заранее )

3(2x+y)-26 = 3x-2y3*2x+3y-26 = 3x-2y-26 + 3y + 6x = 3x-2y-26 + 3y + 6x = -2y + 3x3y + 6x = 26 - 2y + 3x5y + 6x = 26 + 3xx = 26 + 3x / ((5y + 6x)/x)x = 26/3 - 5y/3
15-(x-3y) = 2x+515-x+3y = 2x+515 - x + 3y = 2x+5-x + 3y = -10 + 2x-3x + 3y = -10x = -10 / ((-3x + 3y)/x)x = 10/3 + y
