You got the equation right, but I think it would like you to solve for the variable especially in #3 since it asks 'what is the number'
Answer:
y = (7/4)x + 3
Step-by-step explanation:
(isolate the y variable by moving 7x) 4y = 7x + 12
(divide by 4 to get y by itself) y = (7/4)x + 3
Balanced cause the ground is pushing on it with the same force cause its not go into the ground
