Question

If (2a+5, 3b-8) and (1,4) represent the same point in the
coordinate plane, find the value of a & b.​

Answer 1

Answer:

a = -2   ,     b = 4

Step-by-step explanation:

( 2a + 5 ) = 1

2a = -4

a = -2

( 3b - 8 ) = 4

3b = 12

b = 4

Answer 2

The value of a is -2 and that of b is 4.

Step-by-step explanation:

The given points are (2a+5, 3b-8) and (1,4).

It has been given that these two points represents the same point in the coordinate plane.

Hence, we have

• the x- coordinate of the first point is equal to the x- coordinate of the second point
• and the y- coordinate of the first point is equal to the y- coordinate of the second point.

Thus, we have

2a + 5 = 1

2a = -4

a = -2

And

3b -8 = 4

3b = 12

b = 4

Therefore, the value of a is -2 and b is 4.
