Question

ajuda AE rapaziada, precisando dessas respostas
até às 8:30 tô perdido nessa, agradeço muito msm


a) 2(x+4) = 10x+24 -2

b) 3(x-5) = 1-(2x-4)

c) 2x - 3(4 - x) = 5 + 4(2x + 1)

d) 3(x - 5) +2(2x - 4) = x - 1

e) 2(x - 3) +4(2x + 1) = 8 - 5(x - 4)

f) 50 + (3x - 4) = 2(3x - 4) +26​

Answer 1

Explicação passo-a-passo:

• 2(x+4) = 10x+24 -2
• 2x+8=10x+22
• 2x-10x=22-8
• -8x=14
• X=-14/8(÷2)
• X=-7/4

• 3(x-5) = 1-(2x-4)
• 3x-15=1-2x+4
• 3x+2x=4+1+15
• 5x=20
• X=20/5
• X=4
• 2x - 3(4 - x) = 5 + 4(2x + 1)
• 2x-12+3x=5+8x+4
• 5x-12=8x+9
• 5x-8x=9+12
• -3x=21
• X=-21/3
• X=-7

• 3(x - 5) +2(2x - 4) = x - 1
• 3x-15+4x-8=x-1
• 7x-23=x-1
• 7x-x=-1+23
• 6x=22
• X=22/6(÷2)
• X=11/3

• 2(x - 3) +4(2x + 1) = 8 - 5(x - 4)
• 2x-6+8x+4=8-5x+20
• 10x+2=28-5x
• 10x+5x=28+2
• 15x=30
• X=30/15
• X=2

• 50 + (3x - 4) = 2(3x - 4) +26
• 50+3x-4=6x-8+26
• 46+3x=6x+18
• 3x-6x=18-46
• -3x=-28(-1)
• 3x=28
• X=28/3
