`=> x^2 + 4x + 3 - x^2 + 7x - 10 = 60`
`=> 11x - 7 = 60`
`=> 11x = 67`
`=> x = 67/11`
\(=x^2+3x+x+3-\left(x^2-2x-5x+10\right)=60\)
\(=x^2+4x+3-x^2+2x+5x-10=60\)
\(=11x-7=60\)
11x = 67
=> x = 67 / 11
(x + 1) (x + 3) - (x - 5) (x - 2) = 60
<=> x^2+4x+3-(x^2-7x+10)=60
<=>-3x+13=60
<=>-3x=60-13=47
<=> x=\(\dfrac{-47}{3}\)
\(\left(x+1\right)\left(x+3\right)-\left(x-5\right)\left(x-2\right)=60\)
\(\Leftrightarrow x^2+3x+x+3-x^2+2x+5x-10=60\)
\(\Leftrightarrow11x=67\)
\(\Leftrightarrow x=\dfrac{67}{11}\)
