3\left(3x_{1}+6\right)=4\left(2x+10\right)
Multiply both sides of the equation by 24, the least common multiple of 8,6.
9x_{1}+18=4\left(2x+10\right)
Use the distributive property to multiply 3 by 3x_{1}+6.
9x_{1}+18=8x+40
Use the distributive property to multiply 4 by 2x+10.
8x+40=9x_{1}+18
Swap sides so that all variable terms are on the left hand side.
8x=9x_{1}+18-40
Subtract 40 from both sides.
8x=9x_{1}-22
Subtract 40 from 18 to get -22.
\frac{8x}{8}=\frac{9x_{1}-22}{8}
Divide both sides by 8.
x=\frac{9x_{1}-22}{8}
Dividing by 8 undoes the multiplication by 8.
x=\frac{9x_{1}}{8}-\frac{11}{4}
Divide 9x_{1}-22 by 8.
3\left(3x_{1}+6\right)=4\left(2x+10\right)
Multiply both sides of the equation by 24, the least common multiple of 8,6.
9x_{1}+18=4\left(2x+10\right)
Use the distributive property to multiply 3 by 3x_{1}+6.
9x_{1}+18=8x+40
Use the distributive property to multiply 4 by 2x+10.
9x_{1}=8x+40-18
Subtract 18 from both sides.
9x_{1}=8x+22
Subtract 18 from 40 to get 22.
\frac{9x_{1}}{9}=\frac{8x+22}{9}
Divide both sides by 9.
x_{1}=\frac{8x+22}{9}
Dividing by 9 undoes the multiplication by 9.
