Answer 1

Answer: $x=45$

Simplify both sides of the equation

$x+1.2x+1=100$

$(x+1.2x)+(1)=100$ (Combine Like Terms)

$2.2x+1=100$

Subtract 1 from both sides

$2.2x+1-1=100-1\\2.2x=99$

Divide both sides by 2.2

$2.2x/2.2=99/2.2$

$x=45$

Answer 2

Answer:

Step-by-step explanation:

$x+1.2x+1=100\\\\2.2x+1=100\\\\2.2x=100-1\\\\2.2x=99\\\\x=\frac{99}{2.2}\\\\x=\frac{99*10}{2.2*10}\\\\x=\frac{990}{22}\\\\x=45$
