Answer:

3x-4y=65

3x=65+4y

x=(65+4y)/3, when y=4

x=(65+4*4)/3

x=(65+16)/3

x=81/3

x=27

Answer:

x = 27

Step-by-step explanation:

3x - 4y = 65

Let y= 4

3x - 4(4) = 65

3x -16 = 65

Add 16 to each side

3x-16+16 = 65+16

3x = 81

Divide by 3

3x/3 =81/3

x=27

we have to evaluate the expression for the given value of the variable. i got -16 but it’s supposed to be 48. help??

Dovator [93]

$\bf \cfrac{4(3h-6)}{1+h}\implies \stackrel{\textit{h=-2}}{\cfrac{4[3(-2)-6]}{1+(-2)}}\implies \cfrac{4[-6-6]}{1-2}\implies \cfrac{4[-12]}{-1} \\\\\\ \cfrac{-48}{-1}\implies 48$
