Question

8. Resuelve cada una de las ecuaciones y comprueba las soluciones:
a. 11x – 4 = 8x + 14
b. 1 – 215 = a – 59
c. (–36) + x = –15
d. 56 = 27x
e. –125 m = 448
f. -180w
15 = 205
g. 11x – 4x = 8x + 14
h. 80a + 1,215 = a – 59
i. (–36x) + 8x = –15x

Answer 1

11x – 4 = 8x + 14

11x - 8x = 14 + 4

3x = 18

x = 18/6

x = 3

1 – 215 = a – 59

-214 = a - 59

-214 + 59 = a

155 = a

(–36) + x = –15

-36 + x = - 15

x = -16 + 36

x = 20

56 = 27x

56/27 = x

–125 m = 448

m = - 448/125
