Answer:

no solution

Step-by-step explanation:

STEP 1: Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.

[tex]7x+5-5x=12+2x-8[/tex]

STEP 2: Subtract 5x from 7x.

[tex]2x+5=12+2x-8[/tex]

STEP 3: Subtract 8 from 12.

[tex]2x+5=2x+4[/tex]

STEP 4: Move all terms containing x to the left side of the equation.

[tex]5=4[/tex]

STEP 5: Since 5≠4, there are no solutions.

No solution
