Question

method of substitutiin 5x+y=26, 4x+3y=23
​

Answer 1

Answer:

x+y=3....(1)

4x−3y=26...(2)

Isolate x from equation (1), we get

x=3−y...(3)

Substituting the value of x in equation (2).

4(3−y)−3y=26

or,12−4y−3y=26

or,−7y=14

or,y=−2

Now for x, putting in (3)

x=3−y=3−(−2)=5

Answer : x=5 and y=−2

Answer 2

Step-by-step explanation:

first we find value of x by

5x+y=26

then put value of y on x then find value of x

you got both x or y value
