Question

EQUAÇÃO
1) - 9X +8 = -43
2) - 4=2-3X
3) 0=11X4=-3
4) 2(X-1)+3(X+1)=4(X+2)
5) 2(X) + 18=66

Answer 1

1)  -9x +8= -43
-9x= -43-8
-9x= -51
x=51/9

2) -4= 2-3x
3x=2+4
3x=6
x=6/3
x=2

3) 0= 11x-4
11x-4=0
11x=4
x=4/11

4) 2(x-1) + 3(x+1) = 4(x+2)
2x-2 + 3x+3 = 4x+8
2x+3x-4x= 8+2-3
x=7

5) 2(x) +18= 66
2x +18=66
2x= 66-18
2x=48
x= 48/2
x=24
