Question

7. 3x -5 (2x + 1) = 4x + 6 solve and verify the equation​

Answer 1

Solution:

3x-5(2x+1)=4x+6

3x-10x-5=4x+6

-7x-5=4x+6

4x+7x+6+5=0

11x+11=0

11(x+1)=0

x+1=0

x= -1

verification:

sub X in given eq

3(-1)-5(2(-1)+1)=4(-1)+6

-3-5(-2+1)= -4+6

-3-5(-1)=2

-3+5=2

2=2

therefore X= -1 is true solution for given eq

Answer 2

7.3x-10x-5=4x+6
-2.7x-5=4x+6
2.7x-4x=6+5
-6.7x=11
x=-110/67
