Answer:
When solving for a variable, you undo all operations done to that variable.
In the equation 6x - 3 = -51 we see on the left-hand side that the variable x is being multiplied by 6 and subtracted 3 times.
We can reverse the subtraction operation by using the inverse of subtraction.
Which is the addition operation. If we add 3 to the left-hand side, the -3 term will disappear.
But wait! Anything we do on one side we must do also on the opposite side.
6x - 3 + 3 = -51 + 3
6x = -48
Now how can we undo the multiplication operation done to x?
We can use division. It will make the 6 coefficient disappear!
6x / 6 = -48/6
x = -8
<h3>So, x is equal to -8. (C)

Answer:
Step-by-step explanation:
2 times a number, 2y
the sum of that and 9, 2y+9 ‘is’ 7
2y+9=7
313. Anything .5 or higher rounds up to the higher number.
Hope it helps!
The area is 4 square meters, because 2x2 would be 4
