Simplify \(2x\times 3\) to \(6x\).
\[6x+1+=7x\times 15+3\]
Simplify \(7x\times 15\) to \(105x\).
\[6x+1+=105x+3\]
Subtract \(6x\) from both sides.
\[1+=105x+3-6x\]
Simplify \(105x+3-6x\) to \(99x+3\).
\[1+=99x+3\]
Subtract \(3\) from both sides.
\[1-3=99x\]
Simplify \(1-3\) to \(-2\).
\[-2=99x\]
Divide both sides by \(99\).
\[-\frac{2}{99}=x\]
Switch sides.
\[x=-\frac{2}{99}\]
Decimal Form: -0.020202
x=-2/99
