Question

x+(2x+0.15) + (x+0.05)=1.8

Answer 1

Equation: \[x+(2x+0.15) + (x+0.05)=1.8\]Right?

Answer 2

Hello, @jennydoe? Is that the equation?

Answer 3

Assuming it is:\[x+(2x+0.15) + (x+0.05)=1.8\]
Brackets do not impact in this equation:\[x+2x+0.15+x+0.05)=1.8\]
Simplify\[4x+0.2=1.8\]
Move the \(0.2\) to the RHS
\[4x=1.8-0.2\]\[4x=1.6\]
Divide both sides by \(4\)
\[\frac{4x}{4}=\frac{1.6}{4}\]\[x=0.4\]Do you understand now, @jennydoe?
