Alguem me ajuda por favor galera? Preciso urgente
Equaçoes:
A) 2x=-7
B) x+4(x-1)=9-2(x+3)

Answer 1

A) x = $\frac{-7}{2}$

B) x + 4x -4 = 9 - 2x - 6

2x + 5x = 3 + 4

7x = 7

x = 1

Answer 2

A) X= - 7/2

B) x+4x-4=9-2(x+3)

X+4x-4=9-2x-6

x+4x = 5x-4=9-2x-6

5x-4=3-2x

5x+2x-4=3

7x=3+4

7x=7

X=1
