Question

15x_6y=30,17x+10y=118

Answer 1

Answer:

x=4, y=5

Step-by-step explanation:

15x-6y=30,

17x+10y=118

----------------------------

Write the first one as:

15x-6y=30 => 5x-2y=10 => 2y=5x-10

Substitute y in the second one:  

17x+10y=118 => 17x+5(5x-10)=118 => 42x=168 => x=4

Now find y:

2y=5*4-10 => 2y=10 => y=5

The answer is x=4, y=5
