Solve for x
2x +1 over 5 = -9

=−2 3/5

Step-by-step explanation:

2x-1/5=9

We move all terms to the left:

2x-1/5-(9)=0

2x-9-1/5=0

We multiply all the terms by the denominator

2x*5-1-9*5=0

We add all the numbers together, and all the variables

2x*5-46=0

Wy multiply elements

10x-46=0

We move all terms containing x to the left, all other terms to the right

10x=46

x=46/10
