Answer:
n = -13
Step-by-step explanation:
19 + 10n = 7n - 20
Subtract 7n from each side
19 + 10n-7n = 7n-7n - 20
19+3n = -20
Subtract 19 from each side
19+3n -19 = -20-19
3n = -39
Divide each side by 3
3n/3 = -39/3
n = -13
Y = 3
Just simplify the both sides, then add 7y to both then add 8 to both sides and divide both sides by 15
Well first you have to get 0.4 and turn that decimal into a fraction which will be 2/5 and that fraction is already at its simplest form and cant be reduced so your answer is both 0.4 and 2/5.
