21x=2\left(4x-5\right)
Multiply both sides of the equation by 14, the least common multiple of 2,7.
21x=8x-10
Use the distributive property to multiply 2 by 4x-5.
21x-8x=-10
Subtract 8x from both sides.
13x=-10
Combine 21x and -8x to get 13x.
x=\frac{-10}{13}
Divide both sides by 13.
x=-\frac{10}{13}
Fraction \frac{-10}{13} can be rewritten as -\frac{10}{13} by extracting the negative sign.
