3\left(3x+5\right)-2\left(4x-5\right)=7x+1-30\times 2
Multiply both sides of the equation by 6, the least common multiple of 2,3,6.
9x+15-2\left(4x-5\right)=7x+1-30\times 2
Use the distributive property to multiply 3 by 3x+5.
9x+15-8x+10=7x+1-30\times 2
Use the distributive property to multiply -2 by 4x-5.
x+15+10=7x+1-30\times 2
Combine 9x and -8x to get x.
x+25=7x+1-30\times 2
Add 15 and 10 to get 25.
x+25=7x+1-60
Multiply 30 and 2 to get 60.
x+25=7x-59
Subtract 60 from 1 to get -59.
x+25-7x=-59
Subtract 7x from both sides.
-6x+25=-59
Combine x and -7x to get -6x.
-6x=-59-25
Subtract 25 from both sides.
-6x=-84
Subtract 25 from -59 to get -84.
x=\frac{-84}{-6}
Divide both sides by -6.
x=14
Divide -84 by -6 to get 14.
