Given the system of equation 7x-3y = 48 Eq 1 2x+ y = 35 Eq 2 To solve this system by elimination and multiplication , i can

x = 11.75

y = 11.5

Step-by-step explanation:

By Elimination Method:

   7x - 3y = 48     (1)

-

   2x + y = 35     (2)

Multiply equation (1) by 2 and equation (2) by 7

   14x - 6y = 96

-

   14x + 7y = 245      

     0   -13y = -149

-13y = -149

y = -149/-13

y = 11.5

From equation (2); replace y with 12

2x + y = 35

2x + 11.5 = 35

2x = 35 - 11.5

2x = 23.5

x = 11.75

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

step-by-step explanation:

no solution.
