What is the value of x in the equation 3 x minus 4 y equals 65, when y equals 4?
2 answers:
X=27 Is the answer the rest of them are wrong.
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 each side by 3
3x/3 = 81/3
x = 27
