Question

3(x-5)=7(x+4)-7 pls ans with steps​

Answer 1

Answer:

x= -9

Step-by-step explanation:

3(x-5) = 7(x+4) - 7

As the terms are in brackets when we open the brackets we need to multiply with the term outside bracket.

So,

3x - 3*5 = 7x + 7*4 - 7

3x - 15 = 7x + 28 - 7

3x-15 = 7x + 21

Taking x to one side and the constant to the other,

7x - 3x = -21 + -15

4x =  - 36

x = -36/4

x = -9

Please do mark me brainliest if you think i deserve it :)

Answer 2

3x-15 = 7x+28-7

3x-7x=15+28-7

-4x=15+21

-4x=36

x=36/-4

x= -9
