Question

if 3x-4y=5 is a linear equation such that x=7,then find the value of y.​

Answer 1

3×7-4y=5

21-4y=5

-4y=5-21

-4y=-16

4y=16

y=4

Answer 2

Answer:

y= 4

Step-by-step explanation:

substitute the value of x in given eq then you will get value of y:

3(7)-4y=5

21-4y = 5

21-5=4y

16=4y

y=16/4

y = 4
