Question

Solve and check 2x-1 + 8 =6

Answer 1

Answer:
`x=-1/2`

Simplify both sides of the equation

`2x+-1+8=6`

`(2x)+(-1+8)=6` (Combine Like Terms)

`2x+7=6`

Subtract 7 from both sides

`2x+7-7=6-7\\2x=-1`

Divide both sides by 2

`2x/2=-1/2\\x=-1/2`

Answer 2

x=-1/2

Explanation:

Solving

2x-1+8=6

2x+7=6

2x=6-7

2x=-1

x=-1/2

Checking

put x=-1/2 in equation

LHS 2(-1/2)-1+8

=-1-1+8

=8-2

=6

RHS =6
