b = 2a + 11a + b = 5 which is b = 5 - atherefore2a + 11 = 5 - a (which is b = b)2a + a = - 11 + 53a = - 6a = - 2looking at first equation substitute - 2 for a:b = 2a + 11b = 2*(- 2) + 11b = - 4 +11b = 7to check:a + b = 5- 2 + 7 = 5
1/5+1/11 = 11/55+5/55 = 16/55
-2 + 5 = xsame as:5 - 2 = xx = 3
2x - 5 = 11 2x = 11 + 5 2x = 16 2x /2 = 16 /2 x = 8
x = 5, y = -1
-2 plus 5 equals +3
n=3,y=4 2(n+3y)=30
you add the 5 to both sides of the equation and you have 2x=21 and then you divide by 2 so you have x=11

11 x 2= 22 x+x=2 22 divided by 2= 11 22+11= 33 33-5=28
-2+5=3
