Furkat [3]

Answer:

(2,0)

Step-by-step explanation:

Simply plug in the coordinates. y= 3x - 6, so in this case 0= 3(2) - 6 or 0=0, making the point on the line. If the equation is not true like when using (0,3) and getting 3= -6, then the point is not on the line.

The some of the numbers is 77. The greater number is 5 more than the smaller number.Which equation can be used to solve for the
QveST [7]

Let the smaller number be x and the larger one be y

x + y = 77

y = x + 5

Substituting into the first equation

x + (x + 5) = 77

2x + 5 = 77

Subtracting 5 to both sides

2x +5 -5 = 77-5

2x = 72

Divide both sides by 2

2x/2 = 72/2

x = 36
