Question

if (5,a) is a solution of 3x-2y+5=0 then value of a is​

Answer 1

Answer:

The correct answer is 10

Step-by-step explanation:

Given: 3x-2y+5=0, and points (5,a)

To find: the value of a

3x-2y+5=0

x=5, y=a {given}

put the values in the equation,

after putting the values, we get

3(5)-2(a)+5=0

15-2a+5=0

15+5=2a

20=2a

a=10

the final answer is a=10.

Answer 2

Given,

Solution = 5, a

Equation = 3x-2y+5=0

To find,

The value of a

Solution

We have been given two solutions 5 and a for the equation 3x-2y+5=0

taking the value of x = 5 and y = a and putting them in the equation we get

3x-2y+5=0

-- 3(5) - 2a = -5

-- 15 - 2a = - 5

-- - 2a = - 5 - 15

-- 2a = 20

-- a = 20/2

-- a = 10

Thus the value of a in the equation 3x-2y+5=0 is a = 10
