Question

X+457=839 a*30=150 x-624=281 a/20=9

Answer 1

X+457=839
x=839-457
x=482

x-624=281
x=624+281
x=703

Answer 2

Let's solve the equations step by step:

1. X + 457 = 839: To isolate X, we need to subtract 457 from both sides of the equation: X = 839 - 457 X = 382

2. a * 30 = 150: To isolate a, we need to divide both sides of the equation by 30: a = 150 / 30 a = 5

3. x - 624 = 281: To isolate x, we need to add 624 to both sides of the equation: x = 281 + 624 x = 905

4. a / 20 = 9: To isolate a, we need to multiply both sides of the equation by 20: 20 * (a / 20) = 9 * 20 a = 180

So the solutions to the given equations are: X = 382 a = 5 x = 905 a = 180
