Question

A) ×+×-4=17-2×+1
B) 5×+6×-16=3×+2×-4
C) 5×+4=3×-2×+4
D) 4×+12=1
E) 10×-20=7×+7-3​

Answer 1

A) ×+×-4=17-2×+1

x+x+2x = 17+1+4

4x =22

x = 22/4, simplificando x = 11/2

B) 5×+6×-16=3×+2×-4

5x+6x-3x-2x = -4+16

6x = 12

x = 12/6

x = 2

C) 5×+4=3×-2×+4

5x-3x+2x = +4-4

4x = 0

x = 0/4

x = 0

D) 4×+12=1

4x = 1-12

4x = -11

x = -11/4

E) 10×-20=7×+7-3

10x-7x = +7-3+20

3x = 24

x = 24/3

x = 8

❤️ Bom final de semana ❤️
