Question

What equation has the solution n=-2/3? A: 4n+5=7/3 B: 2n+4/3=1 C: 4n+7/3=5 D: 2n+1=4/3

Answer 1

{ 5 } shows all the numbers from the set {2, 3, 4, 5 }that are part of the solution inequality 4n + 6> 22

Solution:Given inequality is:

Substitute n =

214 is not greater than 22

Thus, n = 2

does not satisfy the given equation

Substitute n = 34(3) + 6 > 2212 + 6 > 2218 is not greater than 22

Thus, n = 3 does not satisfy the given equation

Substitute n = 44(4) + 6 > 2216 + 6 > 2222 is equal to 22

Thus, n = 4 does not satisfy the given equation

Substitute n = 54(5) + 6 > 2220 + 6 > 2226 > 2226 is greater than 22Thus, n = 5 satisfies the given equation

Answer 2

A has the solution of -2/3.
