To solve the first equation:
42 + (x + 28) = 9542 + x + 28 = 95x + 70 = 95x = 95 - 70x = 25
Therefore, x = 25
To solve the second equation:
35 + (x + 31) = 8535 + x + 31 = 85x + 66 = 85x = 85 - 66x = 19
Therefore, x = 19
To solve the first equation:
42 + (x + 28) = 95
42 + x + 28 = 95
x + 70 = 95
x = 95 - 70
x = 25
Therefore, x = 25
To solve the second equation:
35 + (x + 31) = 85
35 + x + 31 = 85
x + 66 = 85
x = 85 - 66
x = 19
Therefore, x = 19
