Answer:
10+10+c+c= 32
Step-by-step explanation:
The perimeter basically equals 2(length+ width) in a rectangle, so we can substitute "c" for the width and 10 inches for the length giving us the equation: 2( 10+ c)= 32 or if we expand 10+ 10+ c+ c= 32

12x-21y=-42 -----> /3 (divided by 3 )
4x-7y=14 ------ (2)
4x-7y=-2 ------- (1)
how 4x-7y =14 an = -2
and if we
(2)-(1)
0=12
