Question

Solve for x given the point (x,9) is a point on the line y = 3x + 7.

Answer 1

0.67 = x

Explanation:

to solve the value of x we need to : (x,9)

y = 3x + 7

9 = 3x + 7

9 - 7 = 3x

2 = 3x

2/3 = x

0.67 = x

Answer 2

From the given point (x , 9) let's plug the value of its y - coordinate of into Equation - y = 3x + 7 and solve for x :

• 
  `9 = 3x + 7`

• 
  `2 = 3x`

• 
  `x = (2)/(3)`

hence, value of x = 2/3
