x + y = 12
Since y=3x, we can stick '3x' in wherever we see 'y':
x + 3x = 12
Tidy up the left side:
4x = 12
Divide each side by 4:
x = 3
y = 9
12 + 5 equals...
a= -0.8
-0.5
The equation seems to equal 72.
y=84-72=12 z=84-52=32 x=84-12-32=40
12 + 5 equals...
a= -0.8
Yes, 12 plus 12 does equal 24.
-0.5
The equation seems to equal 72.
this equals to 12
y=84-72=12 z=84-52=32 x=84-12-32=40
If n + 7 = 12, then n = 12 - 7
-12=m+4 -16=m
Seven plus five equals 12.
7x = 3x - 12 4x=-12 x=-3
no because -12 - +5 changes to -12 + -5 which equals -17
