Answer 1

Respuesta:

i) 8y + 27 = 2y – 3

8y – 2y = –3 – 27

6y = –30

y = $\frac{-30}{6}$

y = –5

j) 7b – 8 = 5b + 4

7b – 5b = 4 + 8

2b = 12

b = $\frac{12}{2}$

b = 6

k) h + 9 = –3h – 7

h + 3h = –7 – 9

4h = –16

h = $\frac{-16}{4}$

h = –4

l) 8x – 5 = 6x – 1

8x – 6x = –1 + 5

2x = 4

x = $\frac{4}{2}$

x = 2

m) 5k + 24 = k – 8

5k – k = –8 – 24

4k = –32

k = $\frac{-32}{4}$

k = –8

n) 8m + 27 = 2m – 3

8m – 2m = –3 – 27

6m = –30

m = $\frac{-30}{6}$

m = –5

o) –4x + 13 = 6x – 7

–4x – 6x = –7 – 13

–10x = –20

x = $\frac{-20}{-10}$

x = 2

p) 3x – 8 = x + 4

3x – x = 4 + 8

2x = 12

x = $\frac{12}{2}$

x = 6
