Question

x-2(x-8)=4x+6

3x+7-(9+3x)=10x-16

-2(4x-15)=-3x​

Answer 1

(x-2)(x-8)=4x+6

x²+8x-2x+16=4x+6

x²+8x-4x-2x= 6-16

x²+2x=-10

x²+2x-10=0

3x+7-(9+3x)=10x-16

3x+7-9-3x=10x-16

3x+7-9-3x-10x-16=0

3x cu -3 x se reduc

-10x= -7+9+16

-10x=18

x=18/10

x=1.8

-2(4x-15)=-3x​

-8x+30=-3x

-8x+3x=-30

-5x=-30 inmultim cu -1

x=30/5

x=6
