7x-5\left(3+2\right)=14\left(2x+x\right)-35
Multiply both sides of the equation by 70, the least common multiple of 10,14,5,2.
7x-5\times 5=14\left(2x+x\right)-35
Add 3 and 2 to get 5.
7x-25=14\left(2x+x\right)-35
Multiply -5 and 5 to get -25.
7x-25=14\times 3x-35
Combine 2x and x to get 3x.
7x-25=42x-35
Multiply 14 and 3 to get 42.
7x-25-42x=-35
Subtract 42x from both sides.
-35x-25=-35
Combine 7x and -42x to get -35x.
-35x=-35+25
Add 25 to both sides.
-35x=-10
Add -35 and 25 to get -10.
x=\frac{-10}{-35}
Divide both sides by -35.
x=\frac{2}{7}
Reduce the fraction \frac{-10}{-35} to lowest terms by extracting and canceling out -5.
