Question

1) 4(x - 3) - 3(x + 2) = -19; 3) -5(7 - X) - 4(x - 8) =3
2) 2x+1+3(x - 2) = 14; 4)2(x - 4) - 5(x-6)=1


​

Answer 1

1)

4(x-3)-3(x+2)=-19

4x-12-3x-6=-19

x=-1

2)

2x+1+3(x-2)=14

2x+1+3x-6=14

5x=19

x=3.8

3)

-5(7-x)-4(x-8)=3

-35+5x-4x+32=3

x=6

4)

2(x-4)-5(x-6)=1

2x-8-5x+30=1

-3x=-21

x=7
