Step 3: Simplify the expression
Step 4: Substitute x=-2 into the formula:
Therefore, the answer is
Thus,
Option B is correct
Answer:
n = -45
Step-by-step explanation:
<u>Turn 2/3n into 2n/3:</u>
2n/3 + 4 = -26
<u>Subtract 4 from both sides:</u>
2n/3 + (4 - 4) = -26 - 4
<u>2n/3 = -30</u>
<u>Multiply 3 from both sides:</u>
2n = -30 * 3
2n = -90
<u>Divide 2 from both sides:</u>
<u>2n = -90</u>
2 = 2
n = -45
To solve for X, you first add the integers together and the X variables together. Then you subtract 3 from each side, followed by dividing by 3 on each side. Here is the work to show our math:
X + X + 1 + X + 2 = 154
3X + 3 = 154
3X + 3 - 3 = 154 - 3
3X = 151
3X/3 = 151/3
X = 50 1/3
Since 50 1/3 is not an integer, there is no true answer to this problem.
