A+4200=9000 7660-a=4782 X•100=88900 b-3705=5000 497+c=5300 X:100=7560 C-98=1300 147+b=5007 90000:x=3

Answer 1

A=9000-4200=4800
a=7660-4782=2878
x=88900:100=889
b=5000+3705=8705
с=5300-497=4803
х=7560*100=756000
с=1300+98=1398
b=5007-147=4860
x=90000:3=30000

Answer 2

Let's solve each of the equations step by step:

1. A + 4200 = 9000 To find the value of A, we subtract 4200 from both sides: A = 9000 - 4200 A = 4800

2. 7660 - a = 4782 To find the value of a, we subtract 4782 from both sides: a = 7660 - 4782 a = 2878

3. X * 100 = 88900 To find the value of X, we divide 88900 by 100: X = 88900 / 100 X = 889

4. b - 3705 = 5000 To find the value of b, we add 3705 to both sides: b = 5000 + 3705 b = 8705

5. 497 + c = 5300 To find the value of c, we subtract 497 from both sides: c = 5300 - 497 c = 4803

6. X:100 = 7560 To find the value of X, we multiply 7560 by 100: X = 7560 * 100 X = 756000

7. C - 98 = 1300 To find the value of C, we add 98 to both sides: C = 1300 + 98 C = 1398

8. 147 + b = 5007 To find the value of b, we subtract 147 from both sides: b = 5007 - 147 b = 4860

9. 90000 : X = 3 To find the value of X, we divide 90000 by 3: X = 90000 / 3 X = 30000

Therefore, the solutions to the given equations are: A = 4800 a = 2878 X = 889 b = 8705 c = 4803 X = 756000 C = 1398 b = 4860 X = 30000
