x + 98
= 74
x + 9 eighths = 7 fourths

x − 0.025 = 0.6
x − 0.025 = 0.6

​x − 78
= −32
​x − 7 eighths = negative 3 halves

x + 0.875 = 1.5

Answer 1

Solve each:

1) x + 9/8 = 7/4 → x = 7/4 − 9/8 = 14/8 − 9/8 = 5/8 = 0.625
2) x − 0.025 = 0.6 → x = 0.6 + 0.025 = 0.625
3) x + 0.875 = 1.5 → x = 1.5 − 0.875 = 0.625
4) x − 7/8 = −3/2 → x = −3/2 + 7/8 = −12/8 + 7/8 = −5/8 = −0.625

Three equations give x = 0.625; the different one is x − 7/8 = −3/2 (it gives x = −5/8).
