Question

a) 2(x+3)=16
b) 5(2x+1) - (x+2)=5x-46

Answer 1

a) 2 ( x + 3 ) = 16
2x + 6 = 16
2x = 16 - 6
2x = 10
x = 10/2
x = 5

v) 5 ( 2x + 1 ) - ( x + 2 ) = 5x - 46
10x + 5 - x - 2 = 5x - 46
10x- x - 5x = - 46 - 5 + 2

4x= - 46 - 3
4x = - 49
x = - 49/4

Answer 2

Olá

Vamos lá


A) 2(x+3)=16
2x+6=16
2x=16-6
2x=10
x=10/2
x=5


b) 5(2x+1) - (x+2)=5x-46
10x+5-x-2=5x-46
10x-x-5x=-46-5+2
4x=-49
x=-49/4

Bons estudos, dúvidas só chamar !!! :>)) erico munayer
