Answer:
y + 4x
Step-by-step explanation:
For this problem, we will simply combine like terms using the distributive property and the commutative property.
First, let's use the commutative property:
2y + x + 3x - y
= 2y - y + x + 3x
Second, let's use the distributive property:
2y - y + x + 3x
= y ( 2 - 1 ) + x ( 1 + 3 )
= y ( 1 ) + x ( 4 )
= y + 4x
Hence, the simplification of 2y + x + 3x - y is y + 4x.
Cheers.
