How you do this:

5x-2=10 you must add 2 to both sides like this 5x-2+2=10+2 you get 5x=12 now divide 5 from each side like this 5/5 x=12/5 you get x=2.4 I hope I helped!

Answer:

$\boxed{\bold{66k+9}}$

Explanation:

Expand $\bold{5\left(10k+1\right): \ 50k+5}$

= $\bold{50k+5+2\left(2+8k\right)}$

Expand $\bold{2\left(2+8k\right): \ 4+16k}$

= $\bold{50k+5+4+16k}$

Simplify $\bold{50k+5+4+16k: \ 66k+9}$

= $\bold{66k+9}$

The solution of the equation is $x=\frac{11}{7}$

Step-by-step explanation:

To simplify an equation of x

Simplify each side of the equation
Collect x in side and the numerical terms in the other side
Find the value of x

∵ The equation is $2x + \frac{1-x}{4}=3$

- Multiply all terms of the equation by 4 to cancel the denominator

of the 2nd term in the left hand side

∵ The equation is $4(2x) +4 (\frac{1-x}{4})=4(3)$

∴ 8x + (1 - x) = 12

∴ 8x + 1 - x = 12

- Add like terms

∴ (8x - x) + 1 = 12

∴ 7x + 1 = 12

- Subtract 1 from both sides

∴ 7x = 11

- Divide both sides by 7

∴ $x=\frac{11}{7}$

The solution of the equation is $x=\frac{11}{7}$
