Question

What is the value of x in the equation 7x + 2y = 48. when y = 3?
x=6
x=7
x=8
x=9

Answer 1

substitute in 3 for y to solve for x. set up the equation 7x+2(3)=48. so that's 7x+6=48. subtract six from both sides to get 7x=42. divide both sides by 7 to get x=6.

Answer 2

If you do the problem correctly It would be x=6
