Question

3) resolva em r as seguintes equações do 1° grau
a)14x+7=3x+5
b)2(x+3)= -3(x+5)

Answer 1

a) 14x+7 = 3x+5
14x-3x = 5-7
11x = -2
x = 2/11

b) 2(x+3) = -3(x+5)
2x+6 = -3x-15
2x+3x = -15-6
5x = -21
x = 21/5

Answer 2

Ola delfrute!

a)=14x+7=3x+5

14x-3x=-7+5
11x=-2
x=-2/11


b)2(x+3)=-3 (x+5)

2x+6=-3x-15
2x+3x=-6-15
5x=-21
x=21/5
