17x+68+8\left(1e+6\right)=11\left(x+5\right)+15\left(x+3\right)
Use the distributive property to multiply 17 by x+4.
17x+68+8e+48=11\left(x+5\right)+15\left(x+3\right)
Use the distributive property to multiply 8 by 1e+6.
17x+116+8e=11\left(x+5\right)+15\left(x+3\right)
Add 68 and 48 to get 116.
17x+116+8e=11x+55+15\left(x+3\right)
Use the distributive property to multiply 11 by x+5.
17x+116+8e=11x+55+15x+45
Use the distributive property to multiply 15 by x+3.
17x+116+8e=26x+55+45
Combine 11x and 15x to get 26x.
17x+116+8e=26x+100
Add 55 and 45 to get 100.
17x+116+8e-26x=100
Subtract 26x from both sides.
-9x+116+8e=100
Combine 17x and -26x to get -9x.
-9x+8e=100-116
Subtract 116 from both sides.
-9x+8e=-16
Subtract 116 from 100 to get -16.
-9x=-16-8e
Subtract 8e from both sides.
-9x=-8e-16
The equation is in standard form.
\frac{-9x}{-9}=\frac{-8e-16}{-9}
Divide both sides by -9.
x=\frac{-8e-16}{-9}
Dividing by -9 undoes the multiplication by -9.
x=\frac{8e+16}{9}
Divide -16-8e by -9.
