127 - 9 x (x + 5) =28
9 x ( x+5 )=127-28
9 x ( x + 5 )=99
X + 5 = 99 : 9
X+ 5 =11
X = 11-5
X =6
127-9x(x+5)=28
9x(x+5) =127-28
9x(x+5) =99
x+5 =99:9=11
x =11-5=6
\(127-9\cdot\left(x+5\right)=28\)
\(9\cdot\left(x+5\right)=127-28\)
\(9\cdot\left(x+5\right)=99\)
\(x+5=99\text{ : }9\)
\(x+5=11\)
\(x=11-5\)
\(x=6\)
127-9x(x+5)=28
\(\Rightarrow\)9x(x+5) =127-28
\(\Rightarrow\)9x(x+5)=99
\(\Rightarrow\)x+5=99:9=11
\(\Rightarrow\)x=11-5=6
