Question

resolva a equação abaixo
a) 10(x+16=14+8)
b) 2(x-3)=-3(x-3)
c) 4(5x-3-64(3-x) -3 (12-4)=96
d)5(x+1)+6(x+2)=9(x+3)​

Answer 1

a) 10x+160=140+80

10x=140+80-160

10x=60

x=60/10

x=6

b)2x-6= -3x+9

5x=15

x=15/5

x=3

c)4(5x-3-192+64x)-3×8=96

4 (69x-195)-24=96

276x-804=96

x900/276 -->75/23

d)5x+5+6x+12=9x+27

11x-9x=27-7

2x=10

x=5
