a) 120 + m = 203
Collect like terms:
120 crosses to the right side of the equality sign to become -120
m = 203 - 120
m = 83
b) d + 59 = 33
Collect like terms:
59 crosses to the right side of the equality sign to become -59
d = 33 - 59
d = -26
b) b + 164 = 95
Collect like terms:
164 crosses to the right side of the equality sign to become -164
d = 95 - 164
d = -69
