Time can vary because sedimentary rocks become magma because of high temperatures and excessive pressure.
Let's solve your equation step-by-step.
2a−8a=12−8a
Step 1: Simplify both sides of the equation.
2a−8a=12−8a
2a+−8a=12+−8a
(2a+−8a)=−8a+12(Combine Like Terms)
−6a=−8a+12
−6a=−8a+12
Step 2: Add 8a to both sides.
−6a+8a=−8a+12+8a
2a=12
Step 3: Divide both sides by 2.
2a
