2\left(x+5\right)=5x-7
Multiply both sides of the equation by 4, the least common multiple of 2,4.
2x+10=5x-7
Use the distributive property to multiply 2 by x+5.
2x+10-5x=-7
Subtract 5x from both sides.
-3x+10=-7
Combine 2x and -5x to get -3x.
-3x=-7-10
Subtract 10 from both sides.
-3x=-17
Subtract 10 from -7 to get -17.
x=\frac{-17}{-3}
Divide both sides by -3.
x=\frac{17}{3}
Fraction \frac{-17}{-3} can be simplified to \frac{17}{3} by removing the negative sign from both the numerator and the denominator.
