Se Poder Me Ajude !

Obg !

Answer 1

x + x + x = 3x
===================
3y + y = 4y
=============================
2ab²c + 5ab²c = 7ab²c
===========================
40x² - 25x² = 15x²
=============================
23,4xy³z - 8,9x³z + 2,5xy³z =
14,5xy³z + 2,5xy³z = 17xy³z
=================================
0,34ab - 2,1ab - ab =
0,34ab - 3,1ab = - 2,76ab
