Answer:
n=1
Step-by-step explanation:
Use the distributive property to multiply 4 by 4−8n.
16−32n−7n=−30+7n
Combine −32n and −7n to get −39n.
16−39n=−30+7n
Subtract 7n from both sides.
16−39n−7n=−30
Combine −39n and −7n to get −46n.
16−46n=−30
Subtract 16 from both sides.
−46n=−30−16
Subtract 16 from −30 to get −46.
−46n=−46
Divide both sides by −46.
n=−46/−46
Divide −46 by −46 to get 1.
n=1
Answer: n = 1
Step-by-step explanation:
Using the distributive law, multiply 4 by what's in the bracket.
(4)(4) -(8n)(4) -7n = -30 + 7n
16 -32n -7n = -30 + 7n
Group all like terms together. Once a (+ve) number goes over the equal sign it now becomes a (-ve) number, vise versa.
16 +30 = 32n + 7n + 7n
46 = 46n
Now we need to find for n. 46n can also be written as 46 multiply by n. When a multiplication sign goes over the equal sign, the sign changes to a division sign.
46 = 46n
46/46 = n
1 = n
