Answer:

x=2

Step-by-step explanation:

6x+2x-9=7

Combine like terms on each side of the equation

8x-9=7

Add 9 to each side

8x=16

Divide by 8 on each side

x=2

Simplifying

6x + -2x + -9 = 7

Reorder the terms:

-9 + 6x + -2x = 7

Combine like terms: 6x + -2x = 4x

-9 + 4x = 7

Solving

-9 + 4x = 7

Solving for variable 'x'.

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

Add '9' to each side of the equation.

-9 + 9 + 4x = 7 + 9

Combine like terms: -9 + 9 = 0

0 + 4x = 7 + 9

4x = 7 + 9

Combine like terms: 7 + 9 = 16

4x = 16

Divide each side by '4'.

x = 4

Simplifying

x = 4

HELP ILL GIVE YOU BRAINLIEST
Alex Ar [27]

Answer:

1. Distributive Property

2. Addition Property of Equality

3. Multiplicative Property of Equality

Step-by-step explanation:

1. The 3 is multiplied by each number in the parenthesis

3*10=30

3*2=6

So 3*(10-2x)=30-6x

2. The 30 is subtracted from both sides

30-6x-30 = -6x

6-30 = -24

30-6x-30=6-30

So -6x=-24

3. The -6 is divided from both sides

-6x/-6 = x

-24/-6 = 4

-6x/-6 = -24/-6

So x=4
