Answer:
D. 
Step-by-step explanation:
First, move the variable (+ 2y) to the left-hand side and change its sign.
Then, move the constant (+ 7) to the right-hand side and change its sign.
Then, collect the like terms (y - 2y)
Finally, add the numbers (3 + 7). That will get you your final answer.
Answer:
5
Step-by-step explanation:

Answer:7x+28
Step-by-step explanation:
7×x = 7x
7×4 = 28
First, to make the equation easier to read, you want to add the x’s together. you should then get 2.6x-3.8=-9. then, you want to add the 3.8 to both sides, to make the x stand alone. you should end up with 2.6x=-5.2. to find x, you then want to divide both sides by 2.6. your final answer after dividing should be x=-2
