4\left(3x+7\right)=7\left(2\times 2+3\right)x
Multiply both sides of the equation by 14, the least common multiple of 7,2.
12x+28=7\left(2\times 2+3\right)x
Use the distributive property to multiply 4 by 3x+7.
12x+28=7\left(4+3\right)x
Multiply 2 and 2 to get 4.
12x+28=7\times 7x
Add 4 and 3 to get 7.
12x+28=49x
Multiply 7 and 7 to get 49.
12x+28-49x=0
Subtract 49x from both sides.
-37x+28=0
Combine 12x and -49x to get -37x.
-37x=-28
Subtract 28 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-28}{-37}
Divide both sides by -37.
x=\frac{28}{37}
Fraction \frac{-28}{-37} can be simplified to \frac{28}{37} by removing the negative sign from both the numerator and the denominator.
