15\left(3x+2\right)+21\times 4\left(x+1\right)=35\times 2\left(x+1\right)
Multiply both sides of the equation by 105, the least common multiple of 7,5,3.
45x+30+21\times 4\left(x+1\right)=35\times 2\left(x+1\right)
Use the distributive property to multiply 15 by 3x+2.
45x+30+84\left(x+1\right)=35\times 2\left(x+1\right)
Multiply 21 and 4 to get 84.
45x+30+84x+84=35\times 2\left(x+1\right)
Use the distributive property to multiply 84 by x+1.
129x+30+84=35\times 2\left(x+1\right)
Combine 45x and 84x to get 129x.
129x+114=35\times 2\left(x+1\right)
Add 30 and 84 to get 114.
129x+114=70\left(x+1\right)
Multiply 35 and 2 to get 70.
129x+114=70x+70
Use the distributive property to multiply 70 by x+1.
129x+114-70x=70
Subtract 70x from both sides.
59x+114=70
Combine 129x and -70x to get 59x.
59x=70-114
Subtract 114 from both sides.
59x=-44
Subtract 114 from 70 to get -44.
x=\frac{-44}{59}
Divide both sides by 59.
x=-\frac{44}{59}
Fraction \frac{-44}{59} can be rewritten as -\frac{44}{59} by extracting the negative sign.
