You plug in the x = 3y+4 into the 3x part of 3x -5y=8. You distribute the 3 and add like terms to end up with 4y=12. You divide by 4 to get y alone and get -1. That’s your y value. You plug that -1 into the y part of any of the two equations to find x. The simplest one is to plug it in to x=3y+4, and you get -3+4=x, so x= -1
Answer: you didnt say or show anything???
Step-by-step explanation:
Answer: 5n = 1.75
Step-by-step explanation:
There are 5”n”s that span the length of the whole (1.75)
-8x+12=-5x,,12=8x-5x,,12=3x ,,x=4
