Question

URGENT PLS!!

consider the system: 5x+3y = 12 , x-7y=10

using elimination method, what is the value of 38y? ​

Answer 1

5x+3y=12

x-7y=10

first you want to make the x the same to 5 since you want to make the x = 0 so you can cancel out the x to find y

5x+3y=12

5x-35y=10

_________

38y = -38

y = -1

to find the x value substitute to any equations it can be the 1st or 2nd

5x+3(-1)=12

x = 3
