Given the equation:
2 x + 3 = 11
we are asked what is the first operation we need to apply in order to solve it.
Since our goal is to isolate the unknown "x" on one side of the equal sign , the first step will be to subtract the numerical term 3 from both sides. The answer then is: Subtraction.
Now we are asked what is the first operation to be done to solve the following equation:
(x/3) - 3 = 11
Again, as we need to isolate the term that contains the x on one side of the equal sign, we woulod porceed by Adding 3 to both sides. Then the answer is: Addition.
We are asked what is the first operation to be done to solve:
11 x + 3 = 3
Again for this case, in order to isolate the term in x we need to Subtract 3 from both sides. Therefore the answer is Subtraction.
Now we are asked what are the steps neede and in order to solve the equation:
3 x + 4 = 13
So we have to start by Subtract 4 from both sides, then divide both sides by 3, as shown below:
3 x + 4 = 13
3 x = 13 - 4 = 9
x = 9 / 3
So, the answer is the last option in the list.
We are asked now to solve for "b" in the following equation:
(b/6) - 2 = 4
so first we add 2 on both sides:
(b/6) = 4 + 2 = 6
and now multiply by 6 both sides to cancel out the 6 that is dividing the unknown "b":
b = 6 * 6 = 36
so b = 36
(last option of the list)
Now we are asked for the steps to solve the equation:
(x/2) - 5 = 20
So first we add 5 to both sides:
(x/2) = 20 + 5 = 25
and then we multiply by 2 both sides to get rid of the 2 which is dividing the x:
x = 25 * 2 = 50
The correct answer is the last option in the list.
Now we are asked to write and solve the equation which represents the following:
"six more than the product of 7 and a number is 55"
We represent the unknown number with "x", Then the product of 7 and the number can be written as "7 x". then 6 more than that can be written as:
6 + 7 x . Then to state that this combination "is" 55, we use the equal sign to represent the "is" statement:
6 + 7 x = 55 or as well 7 x + 6 = 55
now we solve it by first subtracting 6 from both sides:
7 x = 55 - 6 = 49
then we divide both side by 7 in order to isolate x:
x = 49 / 7 = 7
therefore the answer is x = 7.
The correct full set should read: 7 x + 6 = 55; x = 7
Correct answer is the first option.
We are asked to find the price of one pair of shorts given that a person bought two pairs of shorts and a shirt (shirt cost was $22) and the total cost for the purchase was $56.
Since we don't know the price of each pair of shorts, we call it "x". The we can write:
22 + 2 x = 56 (adding all the things included for the total purcahse)
and we proceed to solve for x:
subtract 22 from both sides:
2 x = 56 = 22 = 34
and now divide both sides by 2:
x = 34 / 2 = 17
So each pair of shorts cost $17.
The third opion in the list is the correct one.
