Question

En los siguientes problemas determina X cuando: a=2 b= -3 Y c= -2 (FISICA) X= b+c-a= X=b-c/a X= -b/ac 2aX-b=c

Answer 1

1) X= b+c-a
X = -3+(-2)-(2)
X= -3-2-2
X= -7

2) X = b-c/a
X = -3- (-2/2)
X= -3+1
X= -2

3) X = -b/ac
X = -(-3)/ (2)(-2)
X= +3/-4
X = -3/4

4) 2aX-b = c
2(2)X- (-3) = -2
4X+3= -2
4X = -5
X = -5/4
