10x - 6 = 6x + 14

solve for the letter x

x = 5

Step-by-step explanation:

x = 5

Simplifying

10x + -6 = 6x + 14

Reorder the terms:

-6 + 10x = 6x + 14

Reorder the terms:

-6 + 10x = 14 + 6x

Solving

-6 + 10x = 14 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

-6 + 10x + -6x = 14 + 6x + -6x

Combine like terms: 10x + -6x = 4x

-6 + 4x = 14 + 6x + -6x

Combine like terms: 6x + -6x = 0

-6 + 4x = 14 + 0

-6 + 4x = 14

Add '6' to each side of the equation.

-6 + 6 + 4x = 14 + 6

Combine like terms: -6 + 6 = 0

0 + 4x = 14 + 6

4x = 14 + 6

Combine like terms: 14 + 6 = 20

4x = 20

Divide each side by '4'.

x = 5

Simplifying

x = 5

answer:  

123455421

step-by-step explanation: easy

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
