Answer:
a) x = 34
b) yes, it checks out
Step-by-step explanation:
2x - 5 = 3(4 + 1/2x)
multiply both sides by 2 to eliminate fraction
2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x
x - 10 = 24
x = 34
<u>check</u>
2(34) - 5 = 3(4 + 34/2)
68 - 5 = 3(4 + 17)
63 = 3(21)
63 = 63
You have to use the quadratic formula to solve this. when you do, you get x values of 1.079 and -.5791. You did not provide choices but that's what it comes out to.
Answer:
x = - 8
Step-by-step explanation:
x - 124 = 9(2x + 3) - 15
x - 124 = 18x + 27 - 15
x - 124 = 18x + 12
x - 124 + 124 = 18x + 12 + 124
x = 18x + 136
x - 18x = 18x - 18x + 136
- 17x = 136
- 17x ÷ - 17 = 136 ÷ - 17
x = - 8
