(FORMA FORMAL)

Answer 1

a) c + 504 = 1000
c = 1000 - 504 
c = 496
b) y - 324 = 775
y = 775 + 324
y = 1.099
c) 2.y + 16 = 364
2y = 364 - 16
2y = 348
y = 348/2
y = 174
d)7. a + 50 = 601
7a = 601 - 50
7a = 551
a = 551/7
a = 78,71
e) 2.x - 12 = 124
2x - 12 = 124
2x = 124 + 12
2x = 136
x = 136/2
x = 68
f) 5.z - 410 = 625
5z = 625 + 410
5z = 1035
z = 1035/5
z = 207
g) 8.g + 30 = 784
8g = 784 - 30
8g = 754
g = 754/8
g = 94,25
h) 960 + 3x = 1270
3x = 1270 - 960
3x = 310
x = 310/3
x = 103,3
i) 5.y + 750 = 1250
5y = 1250 - 750
5y = 500
y = 500/5
y = 100
j) 3x + 20 + 40 = 110
3x = 110 - 20 - 40
3x = 50
x = 50/3
x =16,6
k) 6.x + 12 = 772
6x = 772 - 12
6x = 760
x = 760/6
x = 126,6
