Question

-2(x+1/3)+9x=4
EXPLAIN

Answer 1

x = 2/3

Explanation:

- 2 (x + 1/3) + 9x = 4

- 2x - 2/3 + 9x = 4

- 2x + 9x = 4 + 2/3

7x = 4/1 + 2/3

7x = 12/3 + 2/3

7x = 14/3

x = 14/3 / 7

x = 14/3 * 1/7

x = 14/21

x = 2/3

Answer 2

X=2/3=0.66

Explanation:

To solve this problem, first, you have to isolate it on one side of the equation. Isolate x on one side of the equation.

DISTRIBUTIVE PROPERTY:

A(B+C)=AB+AC

A(B-C)=AB-AC

-2(x+1/3)+9x=4

-2(x+1/3)+9x (First, expand by using with distributive property.)

-2(x+1/3)+9x=7x-2/3

7x-2/3=4 (Rewrite the equation problem.)

7x-2/3+2/3=4+2/3 (Add 2/3 from both sides.)

4+2/3 (Solve.)

4+2/3=14/3

7x=14/3

7x/7=14/3/7 (Then, divide by 7 from both sides.)

14/3/7 (Solve.)

14/3/7=2/3

2/3=0.66

x=2/3=0.66

The final answer is x=2/3=0.66.
