Respuesta :
17 = -13 -8x
Add 13 to both sides:
30 = -8x
Divide both sides by -8:
x = 30 / -8
Reduce the fraction by dividing both numbers by 2:
X = -15/4 or - 3 3/4
6 = x +2/3
Subtract 2/3 from both sides:
x = 5 1/3
13 + w/7 = -18
Subtract 13 from both sides:
w/7 = -31
Multiply both sides by 7:
w = -217
Answer:
1) x = -3.75
2) x = 5.33
3) w = -217
Step-by-step explanation:
1) 17 = -13 -8x
Rearranging the terms of the equation:
=> 8x = -13-17
=> 8x = -30
Computing the value of x:
=> x = -30/8 = -15/4 = -3.75
So the required value of x is -3.75
2) 6 = x +2/3
Rearranging the terms of the equation:
=> x = 6-2/3
x = (18-2)/3
Simplifying:
x = 16/3 = 5.33
So the required value of x is 5.33
3) 13 + w/7 = -18
Rearranging the terms of the equation:
=> w/7 = -18-13 = -31
Computing the value of w:
=> w = -31 * 7 = -217
So the required value of w is -217
