Answer:
64 units
Step-by-step explanation:
divide the shape into two shapes:
first one: 15+15+4+4=38
second shape:7+7+6+6=26
pweimwter for the whole shape: 38+26=64 units
3x+7=-x-1
move -x to the other side
sign changes from -x to +x
3x+x+7=-x+x-1
3x+x+7=-1
4x+7=-1
move 7 to the other side
sign changes from +7 to -7
4x+7-7=-1-7
4x=-8
Divide by 4 for both sides
4x/4=-8/4
Answer: x=-2
