4\left(2x+1\right)-5\left(3x+1\right)=100
Multiply both sides of the equation by 20, the least common multiple of 5,4.
8x+4-5\left(3x+1\right)=100
Use the distributive property to multiply 4 by 2x+1.
8x+4-15x-5=100
Use the distributive property to multiply -5 by 3x+1.
-7x+4-5=100
Combine 8x and -15x to get -7x.
-7x-1=100
Subtract 5 from 4 to get -1.
-7x=100+1
Add 1 to both sides.
-7x=101
Add 100 and 1 to get 101.
x=\frac{101}{-7}
Divide both sides by -7.
x=-\frac{101}{7}
Fraction \frac{101}{-7} can be rewritten as -\frac{101}{7} by extracting the negative sign.
