Question

Determine a raiz de cada equação
F) 3(x+3)-1=2
G)3(x+2)-1=2(x+3)-7
H)x -3(4-x)=7x-(1-x)

Answer 1

Vamos lá.

F)

3*(x + 3) - 1 = 2

3*(x + 3) = 3

x + 3 = 1

x = -2

G)

3*(x + 2) - 1 = 2*(x + 3) - 7

2*(x + 3) - 3*(x + 2) = 6

2x + 6 - 3x - 6 = 6

x = -6

H)

x - 3*(4 - x) = 7x- (1 - x)

x - 12 + 3x = 7x - 1 + x

4x - 12 = 8x - 1

4x = -11

x = -11/4
