One number is 18 more than three times another number. The difference in the numbers is 54. Find the numbers

1 answer:

8 0

The equations would be:
x=18+3y
x+y=54
(substitute x in the second equation with 18+3y)
18+3y+y=54
(combine like terms and solve for y)
y=9
(plug y into the second equation to find x)
x+9=54
x=45

10x + 4y = 16 in slope intercept form<br><br>Show your work please

SSSSS [86.1K]

$10x+4y=16\\\\\implies 4y = 16-10x\\\\\implies y =\dfrac14(16-10x)\\\\\implies y = 4 - \dfrac 52 x\\\\\implies y=-\dfrac 52 x +4\\\\\text{This is the slope - intercept form (y=mx+b).}$
