equations with variables on both sides , evaluate each equation 7y + 25 = 2y n + 11 = 2n 7 - 4c = 3c - 7

7y + 25 = 2y

y = -5

n + 11 = 2n

n = 11

7 - 4c = 3c - 7

c = 7

Explanation:

• 7y + 25 = 2y

Subtract 2y from both sides

7y - 2y + 25 = 2y - 2y

5y + 25 = 0

Subtract 25 from both sides

5y + 25 - 25 = 0 - 25

5y = -25

Divide both sides by 5

y = -25/5 = -5

• n + 11 = 2n

Subtract n from both sides

n + 11 - n = 2n - n

11 = n

n = 11

• 7 - 4c = 3c - 7

Add 4c to both sides

7 - 4c + 4c = 3c - 7 + 4c

7 = 7c - 7

Add 7 to both sides

7 + 7 = 7c - 7 + 7

14 = 7c

Divide both sides by 7

c = 14/7 = 7

2

step-by-step explanation:

1+1=2

the answer is c
