I WILL GIVE YOU BRAINLIEST describe the error in solving the equation: 3x-4=2x+1

3x-4-=2x+1-2x

x-4=1

x-4+4=1-4

x=-3

step 1) they should have stated by adding 4 to both sides

The final answer should be x=5

Pls can I have branliest <3 :D

From the above expression we get,

=》x + y = 7 - [1]

=》3x - 2y = 11 - [2]

now, let's solve :

multiplying [1] by 3

=》3x + 3y = 21

=》 3x - 2y = 11

subtracting

now, subtracting [2] from [1]

=》3x + 3y - 3x + 2y = 21 - 11

=》5y = 10

=》y = 2

now, plugging the value of y as 2 in equation [1]

=》x + y = 7

=》x + 2 = 7

=》x = 5

So, value of :
