Solve the following equations. SHOW YOUR WORK.
c – 7 = 7
m – 7 = -7
x + 5 = -10
y + 8 = 3
9k = -18
-3v = – 7
5n = – 15
t/2 = -6
d/-4 = -2
C-7=7
Cancel out the -7 so add 7 to both sides
C-7=7
+7=+7
C=14
M-7=-7
Same thing
M-7=-7
+7=+7
M=0
X+5=-10
-5=-5
X=-15
Y+8=3
-8=-8
Y=-5
9k=-18
This time divide 9 on both sides
9k=-18
\9=\9
K=-2
-3v=-7
/-3=/-3
V=7/3
5n=-15
/5=/5
N=-3
T/2=-6
*2=*2
T=-12
D/-4=-2
*-4=*-4
D=8
