Answer:

a=31

Step-by-step explanation:

Sum = 2a + 15

when this sum is divided by 7 the result is 11:-

2a + 15/7 = 11

2a+ 15 =77

2a= 77-15

2a=62

a = 31

hope this would help

(2a+15)÷7=11

2a+15=11×7 {multiplying by 7 on bith

sides}

2a+15=77

2a=77-15{subtracting 15 from both

sides}

2a=62

Therefore, a=31....{dividing by 2 on

both sides}

Therefore a=31
