Step-by-step explanation:
Answer:
3x/2 + 3y
Step-by-step explanation:
Given the expression 1/4 ( 3x + 4y ) + 3 ( 1/4 x + 2/3 y)
Open the parentheses
= 1/4(3x) + 1/4(4y) + 3(1/4x) +3(2/3y)
= 3/4 x + y + 3/4 x +2y
Collect like terms
3/4 x +3/4 x +y+2y
6/4 x + 3y
3x/2 + 3y
Hence the correct expression is 3x/2 + 3y
Answer:
Step-by-step explanation:
1)w=−4/3x+−1/3y+2/3z+26/3
2)w=−3/2x+1/2y+−1/2z+7
3)w=1/2x+y+3/2z−9
4)w=2x+2y−z−10
