Multiply both sides of the equation by 90, the least common multiple of 3,10,18.
1290x-360+9\left(8x+5\right)=5\left(x-16\right)+1350x-270
Use the distributive property to multiply 30 by 43x-12.
1290x-360+72x+45=5\left(x-16\right)+1350x-270
Use the distributive property to multiply 9 by 8x+5.
1362x-360+45=5\left(x-16\right)+1350x-270
Combine 1290x and 72x to get 1362x.
1362x-315=5\left(x-16\right)+1350x-270
Add -360 and 45 to get -315.
1362x-315=5x-80+1350x-270
Use the distributive property to multiply 5 by x-16.
1362x-315=1355x-80-270
Combine 5x and 1350x to get 1355x.
1362x-315=1355x-350
Subtract 270 from -80 to get -350.
1362x-315-1355x=-350
Subtract 1355x from both sides.
7x-315=-350
Combine 1362x and -1355x to get 7x.
7x=-350+315
Add 315 to both sides.
7x=-35
Add -350 and 315 to get -35.
x=\frac{-35}{7}
Divide both sides by 7.
x=-5
Divide -35 by 7 to get -5.
