Question

$$2X+7=11,or,xX5$$

Answer

X=2,(o*r-7)/2,(5*xX-7)/2

Solution


Regroup terms.
\[2X+7=11,or,5xX\]
Break down the problem into these 3 equations.
\[2X+7=11\]
\[2X+7=or\]
\[2X+7=5xX\]
Solve the 1st equation: \(2X+7=11\).
\[X=2\]
Solve the 2nd equation: \(2X+7=or\).
\[X=\frac{or-7}{2}\]
Solve the 3rd equation: \(2X+7=5xX\).
\[X=\frac{5xX-7}{2}\]
Collect all solutions.
\[X=2,\frac{or-7}{2},\frac{5xX-7}{2}\]
