219-7.(x+1)=10².13

Giúp mik với mai nộp rồi!=)))

Answer 1

219-7.(x+1)=10².13

<=> 219 -7x -7 =100 . 13

<=> 212-7x=1300

-7x=1300 +212

-7x=1512

-x=1512:7

-x=216

x=-216

Answer 2

\(219-7.\left(x+1\right)=10^2.13\)

= \(212.\left(x+1\right)=1300\)

\(\text{= x + 1 = 1300 : 212}\)

= ..........tự tính
