Question

for the eq 3x-2y=17 find the value of x when y=-1 and find the value of y when x=3​

Answer 1

Answer:

x=5 y=-4

Step-by-step explanation:

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.

Answer 2

Given the equation- 3x-2y=17 . Now taking the value of Y=-1 ,we get

3x-2(-1)=17

=>3x+2=17

=>3x=15

=>x= 15/3

=>x=5

Now taking the valueOf when x=3

=>3×3-2y=17

=>9-2y=17

=>-2y=8

=>y=8/-2

=>y=-4
