Question

X+4. (X-1)=9-2. (X+3)

Answer 1

X+4(x-1) = 9-2(x+3)
X + 4x - 4 = 9 -2x -6
5x - 4 = 3 - 2x
7x = 7
x = 7/7 = 1

É isso ;)

Answer 2

X+4(x-1) = 9-2(x+3)
X + 4x - 4 = 9 -2x - 6
5x - 4 = 9 - 6 - 2x
5x - 4 = 3 - 2x
5x + 2x = 3 + 4
7x = 7 ((( o 7 tá multiplicando passa dividindo )))
X = 7/7
X = 1
