Question

the equation is 3x-2y=17. 1) find the value of x when y=-1 2) find the value of y when x = 3​

Answer 1

Given : Equation : 3x-2y=17

Value of y = -1 and value of x = 3

Find : Value of x and y at different conditions.

Solution : Taking first case, here value of y = -1.

Keeping the value in given equation :

3x - 2*(-1) = 17

3x + 2 = 17

3x = 17 -2

3x = 15

x = 5

Taking second case, here value of x = 3.

Keeping the value in given equation :

3*3 - 2y = 17

9 - 2y = 17

2y = 9 - 17

2y = -8

y = -4

Hence, the value of x will be 5 and value of y will be -4.
