Question

The graph of 2x-3=12 crosses the x axis

Answer 1

2x - 3 = 12
     +3    +3
     2x = 9
      2     2
       x = 4 1/2
 (x, y) = (4 1/2, 0)

Answer 2

Where is crosses the x axis is the x intercept
it is also when y=0
so set y to zero
2x-3y=12
2x-3(0)=12
2x-0=12
2x=12
divide by 2
x=6
t
the y intercept=6 or (6,0)
