Answer:
x = 850
Step-by-step explanation:
312·85 + 689·85 - 100x = 85
Divide the whole equation by 85:
312 + 689 - ¹⁰⁰/₈₅.x = 1
1001 - 1 = ²⁰/₁₇.x
x = ¹⁷/₂₀·1000
x = 50 × 17
x = 850
Answer:
x = 271.24
Step-by-step explanation:
312 x 85 + 689 - 100x = 85
Simplify with PEMDAS
Parentheses

Multiplication and
Division
26520 + 689 - 100x = 85
Addition
27209 - 100x = 85
Then use reverse pemdas, SADMEP
Subtraction
-100x = -27124
Finally use Division
x = 271.24
Good luck on the test (is this cheating?)
