Question

solve the following equation and verify your answer:
3(x-7) + 2(x-11) = 4(x-13) - 10​

Answer 1

Answer:

3x-21+2x-22=4x-52-10

5x-43=4x-42

5x-4x=43-42

x=1

Answer 2

Answer:

$3(x - 7) + 2(x - 11) = 4(x - 13) - 10$

$➺3x - 21 + 2x - 22 = 4x - 52 - 10$

$➺3x + 2x - 4x = - 52 - 10 + 21 + 22$

$➺1x = - 19$

$➺x = - 19$

Therefore, The value of x is -19

Now, Verify:

$3( - 19 - 7) + 2( - 19 - 11) = 4( - 19 - 13) - 10$

$➺3( - 26) + 2( - 30) = 4( - 32) - 10$

$➺ - 78 - 60 = - 128 - 10$

$➺ - 138 = - 138$

Hence,

Verified.
