Nancy had 30 stamps and Jane had 154 stamps. After each of them bought x more stamps, Jane had thrice as many stamps as Nancy.Equation in x terms. Value of X?

Respuesta :

Answer:

X = 32

Step-by-step explanation:

Step 0, Set up the equation like this:

3(30 + x) = 154 + x

Step 1, Expand 3(30 + x)

=> 90 + 3x = 154 + x

Step 2, Subtract both side by 90

=> 3x = 64 + x

Step 3, Continue subtract both side by x

=> 2x = 64

Step 4, Divide both side by 2

=> x = 32
