Answer:
Step 1: Add 3y to both sides.
2x−3y+3y=−8+3y
2x=3y−8
Step 2: Divide both sides by 2.
2x
2
=
3y−8
2
x=
3
2
y−4
Answer:
x=
3/2 y -4
x+3y=14
x+3y=14
Step 1: Add -3y to both sides.
x+3y+−3y=14+−3y
x=−3y+14
Answer:
x=−3y+14

Answer:
8c - 7r + 10p - 20e
Step-by-step explanation:
Subtract (20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)
(20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)
Open bracket
20c + 15r + 75p + 50e - 12c - 22r - 65p - 70e
Collect like terms
= 20c - 12c + 15r - 22r + 75p - 65p + 50e - 70e
= 8c - 7r + 10p - 20e
