Question

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

Answer 1

Olá,boa tarde ☺

a)

10x+16=14x+8
10x-14x= 8 - 16
-4x= -8
4x=8
x=8/4
x=2

b)

2(x-3)= -3(x-3)
2x-6= -3x + 9
2x + 3x = 9 + 6
5x=15
x=15/5
x=3

c)

4(5x-3)-64(3-x)-3(12x-4)=96
20x - 12 - 192 + 64x - 36x + 12= 96
20x+64x-36=96+12+192-12
48x=288
x=288/48
x=6

d)

5(x+1)+6(x+2)=9(x+3)
5x+5+6x+12=9x+27
5x+6x-9x=27-5-12
11x-9x=27-5-12
2x=10
x=10/2
x=5

Bons estudos :)
