Answer:

x = 11(13/14)

Step-by-step explanation:

3/5(x – 7/10) = -31/4

open the bracket:

3/5 * x – 7/10 = -31/4

3/5 * –7x/10 = -31/4

3/5 + 31/4 = 7x/10

(12+155)/20 = 7x/10

167/20 = 7x/10

cross multiply:

140x = 1670

x =1670/140

x = 11(130/140)

x = 11(13/14)
x=11(13/14)
Step-by-step explanation:
3/5(x-7/10) = -31/4
open the bracket:
3/5 * x-7/10 = -31/4
3/5*-7x/10 =-31/4
3/5 + 31/4 = 7x/10
(12+155)/20 = 7x/10°
167/20 = 7x/10
cross multiply:
140x = 1670
x=1670/140
x=11(130/140)
x = 11(13/14)
