What is the solution of 3x+y=9 and 3x-5y=15

Step-by-step explanation:

Two equations are 3x + y = 9 (1)

and 3x - 5y = 15 (2)

we have to calculate the value of x common for both.

We multiply equation 1 by 5 and add it to equation 2

15x + 5y = 45

3x - 5y = 15___

18x = 60

x = 60/18 = 10/3

y=-x+3   y=3/5-3

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:
