15+143+2x(X+3)=2x(15-7x5)x101

Answer 1

15 + 143 + 2 × ( x + 3 ) = 2 × ( 15 - 7 × 5 ) × 101

158 + 2 x + 6 = 2 × ( 15 - 35 ) × 101

2 x + 164 = 2 × ( - 20 ) × 101

2 x = - 4 040 - 1 64

2 x = - 4 204

x = ( - 4 204 ) : 2

x = - 2 102

Answer 2

15+143+2•(x+3)=2•(15-7•5)•101=

15+143+2•(x+3)=2•(15-35)•101=

15+143+2•(x+3)=2•-20•101=

15+143+2•(x+3)=-4040

2•(x+3)+158=-4040

2•(x+3)=-4040-158=-4198

$x + 3 = - \frac{4198}{2} = - 2099$

x=-2099-3=-2102
