Question

find x , if 4x+3y=25 and y=5​

Answer 1

Step-by-step explanation:

Given:

y = 5 ----> equation 1

4x + 3y = 25 ----> equation 2

Solution:

Putting y = 5 in equation 2 we get ,

4x + 3y = 25

4x + 3(5) = 25

4x + 15 = 25

4x =25-15 ( + becomes - on sending to other side)

4x= 10

x = 10/4

x= 5/2

Therefore ,

The value is x= 5/2
