Answer:

We proved that [tex]-3(2x+7) = -29 - 4x[/tex] gives [tex]\mathbf{x=4}[/tex]

Step-by-step explanation:

We are given: [tex]-3(2x+7) = -29 - 4x[/tex]

We need to prove x=4

Statements                            Reasons

[tex]-6x-21=-29-4x[/tex]                  Distributive property of multiplication over subtraction

[tex]-6x-21+4x=-29-4x+4x[/tex]            Addition property of equality

[tex]2x-21=-29[/tex]                               Additive inverse property (+4x-4x=0)

[tex]2x-21+21=-29+21[/tex]             Addition property of equality

[tex]2x=8[/tex]                                          Additive inverse property

[tex]2x/2=8/2[/tex]                                  Division property of equality

[tex]x=4[/tex]                                           Answer

So, We proved that [tex]-3(2x+7) = -29 - 4x[/tex] gives [tex]\mathbf{x=4}[/tex]
