Answer:
1. d=183
2. h=8
3. z=7
4. x= 8
Step-by-step explanation:
1.) 453 + 364 + d = 1000 (transpose)
d= 1000-453-364
d=183
2.) 8h = 20 + 44
8h=64 (divide both side by 8)
h=8
3.) 5z + 10 = 20 + 25
5z=20+25-10
5z=35 (divide both side by 5)
z=7
4.) 3x + 4 = 28
3x = 28-4
3x=24 (divide both side by 3)
x= 8
Answer:
1. d = 183
➽ 453 + 364 + 183 = 1000
2. h = 8
➽ 8•8 = 20 + 44
3. z = 7
➽ 5•7 + 10 = 20 + 25
4. x = 8
➽ 3•8 + 4 = 28
