Answer:
x/2x+3 + 2x +3/x = 184 /65
x(2x + 3)–1 + (2x+3)x-1 = 184/65
(2x + 3)x / (2x +3)x = 184/65
2x² + 3x / 2x² + 3x = 184/65
1x= 184/64
x = 184/64
Answer:
7
Step-by-step explanation:
Answer:
23x = -115
Step-by-step explanation:
In the substitution method, you must solve for 1 variable in 1 equation to replace it in the other equation. For the system:
2x - 7y = 4
3x + y = -17
Solving for y in the second equation:
y = -17 - 3x
Replacing y in the first equation:
2x - 7(-17 - 3x) = 4
2x + 119 + 21x = 4
23x = -115
This is the new equation after use the substitution method.
The answer is 8.45498149331, you can round it to the nearest thousandths place though, too.
