Question

Solve and verify
8x+4 = 3[x-1]+7
Please write the steps...

Answer 1

Answer:

4

Step-by-step explanation:

8x+4=3[x-1]+7

8x+4=3x-3+7

8x+4=3x+4

By transposition,{the sign get reverse when moved from one side to another}

8x-3x = -4+4

5x = 0

x= 0/5=0

Verification. x=0

8*0+4=3{0-1}+7

0+4=3*-1+7

4= -3+7

4=4

LHS=RHS

Answer 2

8x+4=3(x-1)+7

=8x+4=3x-3+7{I opened the bracket}

=8x-3x=7-3-4

=5x=0

=X=0

Now, let's check:

8(0)+4=4

& 3(0-1)+7=3(-1)+7

=4

=>LHS=RHS hence, verified.
