36-42\left(2+x\right)=7\left(x+4\right)-7\left(3x+1\right)
Multiply both sides of the equation by 42, the least common multiple of 7,6.
36-84-42x=7\left(x+4\right)-7\left(3x+1\right)
Use the distributive property to multiply -42 by 2+x.
-48-42x=7\left(x+4\right)-7\left(3x+1\right)
Subtract 84 from 36 to get -48.
-48-42x=7x+28-7\left(3x+1\right)
Use the distributive property to multiply 7 by x+4.
-48-42x=7x+28-21x-7
Use the distributive property to multiply -7 by 3x+1.
-48-42x=-14x+28-7
Combine 7x and -21x to get -14x.
-48-42x=-14x+21
Subtract 7 from 28 to get 21.
-48-42x+14x=21
Add 14x to both sides.
-48-28x=21
Combine -42x and 14x to get -28x.
-28x=21+48
Add 48 to both sides.
-28x=69
Add 21 and 48 to get 69.
x=\frac{69}{-28}
Divide both sides by -28.
x=-\frac{69}{28}
Fraction \frac{69}{-28} can be rewritten as -\frac{69}{28} by extracting the negative sign.
