the sum of two times x and 3 times y is 5. the difference of x and y is 5 write two equations and fine the value of y

y = - 1

Step-by-step explanation:

Details have been given in the question, we need to break them apart and create our equations accordingly.

"the sum of two times x and 3 times y is 5"

2x + 3y = 5

"the sum of two times x and 3 times y is 5"

x - y = 5

So, our two equations are:

2x + 3y = 5

x - y = 5

Solve using substitution method, by moving y to the other side.

x = y + 5

2 (y + 5) + 3y = 5

2y + 10 + 3y = 5

Combine like terms

5y + 10 = 5

Subtract 10 from both sides

5y = - 5

y = - 1
