First, you must use ADDITION to find -12 + 8 (-4)
Then, use MULTIPLICATION to find -4*2 (16
1) Addition
2) Multiplication
Top left:
7x-44 = 4x+4
7x-4x = 4+44
3x = 48
x = 16
8y-43 = 39+(7(16)-44)
8y = 39+68+43
8y = 150
y = 18.75
A) Gigabytes = x
B) 35+5x = 25+10x
10 = 5x
2 = x
C) After 2 gigabytes, the wireless services will cost the same ($45)
