\(11\cdot\left(x-6\right)=4x+11\)
\(11x-66=4x+11\)
\(11x-4x=11+66\)
\(7x=77\)
\(\Rightarrow x=11\)
\(11.\left(x-6\right)=4x+11\)
=) \(11x-66=4x+11\)
=) \(11x-4x=11+66\)
=) \(7x=77\)
=) \(x=77:7=11\)
11.(x-6)=4x+11
11.x-66=4x+11
7x=66+11
7x=77
x=11
vậy x=11
Minh thich thi minh lam
\(11\cdot\left(x-6\right)=4x+11\)
\(\Leftrightarrow11x-4x=11+66\)
\(\Leftrightarrow7x=77\)
\(\Leftrightarrow x=\frac{77}{7}\)
\(\Leftrightarrow x=11\)
nè cậu sai rùi 4*+11 lam sao lam duoc 2 dau kia
\(11.\left(x-6\right)=4x+11\)
\(11x-\left(11.6\right)=4x+11\)
\(11x-66=4x+11\)
\(11x-4x=11+66\)
\(7x=77\)
\(x=77\div7\)
\(x=11\)
11. ( x - 6 ) = 4x + 11
11x - 66 = 4x + 11
11x - 4x = 11 + 66
11x - 4x = 77
7x = 77
=> x = 77 ÷ 7
=> x = 11
