<em>a = 5</em>
- Step-by-step explanation:
<em>a(2x + 3) = 9x + 15 + x</em>
<em>a(2x + 3) = 10x + 15</em>
<em>a(2x + 3) = 5(2x + 3)</em>
<em>a = 5(2x + 3)/(2x + 3)</em>
<em>a = 5</em>
Answer:
Ashley=13 messages
Frank=20 messages
Chang=2x+14=40 messages
Step-by-step explanation:
Number of texts sent by each person;
Ashley=x
Frank=x+7
Chang=2(x+7)=2x+14
Total number of text messages=Number sent by Ashley+Number sent by Frank+Number sent by Chang
where;
Total number of text messages=73
Replacing;
73= x+(x+7)+(2x+14)
x+x+2x+7+14=73
4x+21=73
4x=73-21
4x=52
x=52/4
x=13
Ashley=13 messages
Frank=x+7=13+7=20 messages
Chang=2x+14=(2×13)+14=40 messages
