Answer:
−7.389056fo3+5.436564f
−l2o3+2l
Step-by-step explanation:
2al+f(2.7182822)o3=al2o3+2f(2.718282)
Step 1: Add -al^2o^3 to both sides.
7.389056fo3+2al+−al2o3=al2o3+5.436564f+−al2o3
−al2o3+7.389056fo3+2al=5.436564f
Step 2: Add -7.389056fo^3 to both sides.
−al2o3+7.389056fo3+2al+−7.389056fo3=5.436564f+−7.389056fo3
−al2o3+0fo3+2al=−7.389056fo3+5.436564f
Step 3: Factor out variable a.
a(−l2o3+2l)=−7.389056fo3+5.436564f
Step 4: Divide both sides by -l^2o^3+2l.
a(−l2o3+2l)
−l2o3+2l
=
−7.389056fo3+5.436564f
−l2o3+2l
a=
−7.389056fo3+5.436564f
−l2o3+2l
