Answer:
2 + 7 x y
Step-by-step explanation:
81 - 35+30 (55) = 26 therefore 26cm is ur final answer
Answer: D. 3y + 5 − 7y = 4(-y + 1) + 5
Step-by-step explanation:
Original equation:
3y + 5 - 7y = 4(-y+1) + 5
Group like terms on the left of the equal sign and distribute on the right side of equal sign:
-4y + 5 = (-4y +4) + 5
Simplify:
-4y + 5 = -4y +9
Subtract 5 from both sides:
-4y = -4y + 4
Add 4y to both sides:
0 = 4
0 CANNOT equal 4 therefore, this equation has no solution.
