Solve this simultaneous equation: 6x+2y = 26 and 8x + 3y = 32

If 6x + 2y = 26 then 26 - 6x = 2yy = 13 - 3xSo, using the substitution method.... into 8x + 3y = 328x + 3(13 - 3x) = 328x + 39 - 9x = 32-x + 39 = 3232 + x = 39x = 39 - 32 = 7Sub x = 7 into 6x + 2y = 266(7) + 2y = 2642 + 2y = 262y = 26-42 = -16y = -8Check in other equation: 8x + 3y = 328(7) + 3(-8) = 56 - 24 = 32
