Answer:


\boxed{ \bold{ \mathsf{ \purple{x = - 13}}}}

Explanation:


\mathsf{2x - 3x + 5 = 18}

Collect like terms


\mathsf{ - x + 5 = 18}

Move constant to R.H.S and change it's sign


\mathsf{ - x = 18 - 5}

Calculate the difference


- x = 13

Change the signs on both sides of the equation


\mathsf{x = - 13}

\mathsf{LHS \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: RHS}


\mathsf{2x - 3x + 5 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 18}


\mathsf{ = 2 * ( - 13) - 3 * ( - 13) + 5}


\mathsf{ - 26 + 39 + 5}


\mathsf{ = 13 + 5}


= 18

Thus, LHS = RHS

hope I helped!

Best regards!

Hi my lil bunny!

Let's solve your equation step-by-step.


2x-3x+5=18

Step 1: Simplify both sides of the equation.


2x-3x+5=18\\2x + -3x + 5 = 18


( 2x + -3x ) + ( 5) = 18 (Combine Like Terms)


-x + 5 = 18\\-x + 5 = 18

Step 2: Subtract 5 from both sides.


-x + 5 - 5 = 18 - 5 \\-x = 13

Step 3: Divide both sides by -1.


(-x)/(-1) = (13)/(-1) \\x = -13

Answer :
\boxed {x = -13}
