ECUACIONES LINEALES
-x+10+12=44-9+66

24-(x+7)=12+2(9-2x)

Answer 1

-x+10+12=44-9+66

-x+22=35+66

-x +22 = 101

22-101 = x

-79 = x


24-(x+7)=12+2(9-2x)

24-x-7 = 12 +18 -4x

31 - x = 30 - 4x

4x - x= 30 -31

3x = -1

x = -1/3

Answer 2

-x+10+12=44-9+66
-x=44-9+66-10-12
-x=100-31
-×=69
x=-69

24-(x+7)=12+2 (9-2x)
24-x-7=12+18-4x
-x+4x=12+18+7-24
3×=13
x=13/3
