the answer is -10. First subract 7 from both sides to get negative 4 on the right sides of the equation. Then multiply each sides by 5. The 5 will cancel out with the 5 in the denominator of 2n/5 and give you -20 on the other side of the equation. Then divide each side by 2 and then you get -10.

Subtract 7: 2n/5 = –4
Multiply by 5: 2n = –20
Divide by 2: n = –10
the answer is -10. First subract 7 from both sides to get negative 4 on the right sides of the equation. Then multiply each sides by 5. The 5 will cancel out with the 5 in the denominator of 2n/5 and give you -20 on the other side of the equation. Then divide each side by 2 and then you get -10.
First, move the 7 to the other side of the equation by subtracting 7:
2n/5 + 7 = 3
2n/5 = -4
Now set it up as a cross multiplication problem:
2n/5 = -4/1
Now cross multiply:
2n = -20
Now divide by 2 to solve for n:
2n/2 = -20/2
n = -10
2n/5+7=3
I assume ( I know that's scary) that it's
(2n/5)+7=3
so multitply both sides by 5 to get rid of the fraction (keeps it an equation)
2n + 35 = 15
subtract 35 from both sides
2n = -20
and I'm tired - you have it from here
all the best
Do the same thing to both sides to solve it: 2n/5+7=3
Subtract 7 from both sides: -7 -7
You get: 2n/5 = -4
Then, multiply both sides by 5: x5 x5
You get: 2n = -20
Then, divide both sides by 2: n = -10
Multiply both sides by 5 :~ 2n + 35 = 1
Subtract 35 from each side :~ 2n = -20
Divide both sides by 2 :~ n = -10
First get your term with n by itself. So you get:
2n/5=3-7
2n/5=-4
Multiply both sides by 5 to get:
2n=-20
Divide both sides by 2 to get:
n=-10
2n/5+7=3
2n/5 = 3-7
2n/5 = -4
2n = -20
n = -20/2
n = -10
n = -10
2n/5 + 7 = 3
2n/5 = 3-7
2n = (3-7)*5
n = -20/2
n = -10
2n/5 + 7 = 3
2n/5 = -4
2n = -20
n = -10
Best of luck!
