2x - 5y = 11. (4, a). x = 4, y = a
Substituting into 2x - 5y = 11
2(4) - 5(a) = 11
8 - 5a = 11
-5a = 11 - 8
-5a = 3
a = 3/-5 = -3/5 =- 0.6
Other coordinate = -3/5 = -0.6

Answer:
B.) 6
2.) 70
3.) 56
Step-by-step explanation:
B.) 2(6) - 6
= 12 - 6
=6
2.) 7(2(3)+4)
=7(6+4)
=42+28
=70
3.) 10(3) + 4(3) + 14
= 30 + 12 + 14
= 42+14
=56
Have a wonderful day
