Answer:


\boxed{ \bold{ \huge{ \boxed{ \sf{x = 7}}}}}

Explanation:


\sf{2x + 8 + 3x + 6 = 7x}

Add the like terms : 2x and 6


\dashrightarrow{ \sf{5x + 8 + 6 = 7x}}

Add the numbers : 8 and 6


\dashrightarrow{ \sf{5x + 14 = 7x}}

Move 7x to left hand side and change it's sign

Similarly, move 14 to right hand side and change it's sign


\dashrightarrow{ \sf{5x - 7x = -14}}

Subtract 7x from 5x


\dashrightarrow{ \sf{ - 2x = - 14}}

Divide both sides by -2


\dashrightarrow{ \sf{ ( - 2x)/( - 2) = (-14)/( - 2)}}

Calculate


\dashrightarrow{ \boxed{ \sf{x = 7}}}

Hope I helped!

Best regards! :D

Answer:

x=7 Hope this helps :)

Explanation:

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

2x+8+3x+6=7x

Step 1: Simplify both sides of the equation.

2x+8+3x+6=7x

(2x+3x)+(8+6)=7x(Combine Like Terms)

5x+14=7x

5x+14=7x

Step 2: Subtract 7x from both sides.

5x+14−7x=7x−7x

−2x+14=0

Step 3: Subtract 14 from both sides.

−2x+14−14=0−14

−2x=−14

Step 4: Divide both sides by -2.

−2x

−2

=

−14

−2

x=7
