15x-70=2\left(6x-0\times 5\right)
Use the distributive property to multiply 5 by 3x-14.
15x-70=2\left(6x-0\right)
Multiply 0 and 5 to get 0.
15x-70-2\left(6x-0\right)=0
Subtract 2\left(6x-0\right) from both sides.
15x-70-2\times 6x=0
Reorder the terms.
15x-70-12x=0
Multiply -2 and 6 to get -12.
3x-70=0
Combine 15x and -12x to get 3x.
3x=70
Add 70 to both sides. Anything plus zero gives itself.
x=\frac{70}{3}
Divide both sides by 3.
