7x - 4y + 8=0 slope intercept is y=mx+b so you have to get y alone
+4y =+4y so add for y on both sides
7x + 8=4y Then divided 4y on both sides
7x/4 8/4= 4y/4
slope intercept form is y=7/4x+2
Lets call your age x and your sisters would be x +2
x + x + 2 = 32
combine like terms
2x + 2 = 32
32 - 2 = 2x
32 - 2 = 30
2x = 30
x = 15
Your age is 15 and your sisters is 17
