Question

substitution method
2x+3y=13
4x+5y=23​

Answer 1

ANSWER

multiply the first equation by 4, the second by 2, add:

multiply the first equation by 4, the second by 2, add:8x + 12y = 52

multiply the first equation by 4, the second by 2, add:8x + 12y = 52subtract these two equations

multiply the first equation by 4, the second by 2, add:8x + 12y = 52subtract these two equations8x + 10y = 46

multiply the first equation by 4, the second by 2, add:8x + 12y = 52subtract these two equations8x + 10y = 46______________

multiply the first equation by 4, the second by 2, add:8x + 12y = 52subtract these two equations8x + 10y = 46______________2y = 6 Divide 2

multiply the first equation by 4, the second by 2, add:8x + 12y = 52subtract these two equations8x + 10y = 46______________2y = 6 Divide 2y=3
