12x15=18(3x+4)
180=54x+72
-72 -72
108=54x
/54 /54
2=x
X=2 the other person is a d0uche for answering like that so I answered instead of them
Answer: 9.6
Step-by-step explanation: A rational number can be written as a ratio of two integers (9.6 can write as 96/10)
Step by step:
GR-8 = 34x - 12
• move variable to left hand side
-34x + gr -8 = - 12
• change expression and move to right side
-34x = - 12 - gr - 8
• calculate sum
-34x = - 4 - gr
• divide both sides
X = 2/17 + 1/34gr
And there’s your answer :)
Answer:
No solution
Step-by-step explanation:
4x + y = -2
-20x - 5y = -3
<u><em>Using the Elimination method </em></u>
(4x + y = -2 ) 5
20x + 5y = -10
-20x - 5y = -10
0 = -10
