Step-by-step explanation:
The equivalent expression of 8x + 12 - x = 7x + 12
X + y = 3500 -------------- (1)
x - y = 2342 --------------- (2)
(1) + (2):
2x = 5842
x = 2921 -------------- Sub into (1)
x+ y = 3500
2921 + y = 3500
y = 3500 - 2921
y = 579
----------------------------------------------
Answer: x = 2921, y = 579

Answer:
4x+7z
Step-by-step explanation:
4x + 2z + z +4z is the expression
The simplified expression is just the terms combined
so,
4x + 2z+1z+4z
4x+3z+4z
4x+7z
