a. -6x + 220 = -566
b. 0,8m - 3,2 = 8 - 4,8m
c. 151u + 411= 203 - 109u
d. -4(b + 2) + b = -4(1+ b)
Thanks in advance!
-6x + 220 = -566
-6x = -786
x = 131
0.8m - 3.2 = 8 - 4.8m
5.6m = 11.2
m = 2
151u + 411 = 203 - 109u
260u = -208
u = -0.8
-4(b+2) + b = -4(1+b)
-4b - 8 + b = -4 - 4b
-8 + b = -4
b = 4
