Question

Q. Verify by substitution

x=1 is the solution of 4x – 1=3
1

is the solution of 3 - 9x = 0
3

X = 2 is the solution of 2x - 2 = 5x - 8

x = -1 is the solution of -3x = 3

y =1 is the solution of 8 – 7 y = 1​

Answer 1

Answer:

Here is your answer:-

$x = 1 \\ 4x - 1 = 3 \\ 4(1) - 1 = 3 \\ 4 - 1 = 3 \\ 3 = 3 \: \\ \\ x = 1 \\ 3 - 9x = 0 \\ 3 - 9(1) = 0 \\ 3 - 9 = 0 \\ 6 = 0$

rest will be same
