Answer

{$3$}

Work Step by Step

Step 1: $0.01x+3.1=2.03x-2.96$ Step 2: Subtracting $0.01x$ from both sides, $0.01x-0.01x+3.1=2.03x-0.01x-2.96$ Step 3: $3.1=2.02x-2.96$ Step 4: Adding $2.96$ to both sides, $3.1+2.96=2.02x-2.96+2.96$ Step 5: $6.06=2.02x$ Step 6: Dividing both sides by $2.02$, $\frac{6.06}{2.02}=\frac{2.02x}{2.02}$ Step 7: Therefore, $x=3$. Check: $0.01(3)+3.1=2.03(3)-2.96$ $0.03+3.1=6.09-2.96$ $3.13=3.13$ $0=0$ Since the result checks, the solution set of the equation is {$3$}.
