t)7×+8=4×-10​

me ajudemmm

Answer 1

Explicação passo-a-passo:

p)12×-144=9×+9

12x-9x = 9 + 144

3x = 153

x = 153/3

x = 51

q)18×-220=3×+5

18x-3x = 5 + 220

15x = 225

x = 225/15

x = 15

r)17×-186=3×+10

17x-3x = 10 + 186

14x = 196

x = 196/14

x = 14

s)3×-7=2×+5

3x-2x = 5+7

x = 12

t)7×+8=4×-10

7x-4x = - 10 - 8

3x = - 18

x = - 18/3

x = - 6
