Question

If (a, 10) be a point on the straight line 3x = 17 - 2y then the value of a is:
a = -2
(B)
a = 2
(C)
= -1
(D)
a = 1​

Answer 1

Answer:

value of a = -1 (option c)

Step-by-step explanation:

the co-ordinates are a,10

therefore x = a

and y = 10

in the equation put y = 10;

3x = 17-2y

3x = 17 - 2×10

3x = 17 - 20

3x = -3

x = -3/3

x = -1
