Question

15=7-4(6-r) solve the equation class 7​

Answer 1

Answer:

r=8

Step-by-step explanation:

7-4(6-r)=15

7-24+4r=15

4r=15-7+24

4r=8+24

4r=32

r=32/4

r=8

Answer 2

Step-by-step explanation:

$15 = 7 - 24 - 4r \\ 15 = - 16 - 4r \\ 15 + 16 = 4r \\ 31 = 4r \\ r = \frac{31}{4} \\ r = 7.75$
