Since you divide by a negative, you must flip the sign.
Answer:
X= -1
Step-by-step explanation:
So to solve equations like this, you want to isolate the variable first. Then you begin to simplify by dividing each side of the equation by a factor that does not contain a variable.
Answer:
-5x-15
Step-by-step explanation:
its simple you have to multiply it to both
Answer:
the first one
Step-by-step explanation:
the first one
1/2(x - 7) = 11
<em><u>Distributive property.</u></em>
0.5x - 3.5 = 11
<em><u>Add 3.5 to both sides.</u></em>
0.5x = 14.5
<em><u>Multiply both sides by 2.</u></em>
x = 29. (This is your answer.)
We can plug 29 into the original equation to verify.
1/2(x - 7) = 11
1/2(29 - 7) = 11
1/2(22) = 11
11 = 11 √ This is correct.
