Question

Calculando a equação 3(x-5)+2(2x-4)=x- 1 , descubra o valor de x A) 3/11B) 11/3C) 9/10D) 11/9

Answer 1

3(x-5)+2(2x-4)=x-1
3x-15+4x-8=x-1
7x-23=x-1
7x-x=-1+23
6x=22
x=22/6(÷2)
x=11/3

Answer 2

3(x-5) +2 (2x-40 = X-1


3X -15+4X -8 = X-1


7X -23 =X-1


7X-X = 1 +23


6X = 22

X=22/6

X= 11/3
