Answer:
w = 5/8 or decimal w = 0.625
Step-by-step explanation:
Solve for w:
26 - 7 w = w + 21
Subtract w from both sides:
26 + (-7 w - w) = (w - w) + 21
-7 w - w = -8 w:
-8 w + 26 = (w - w) + 21
w - w = 0:
26 - 8 w = 21
Subtract 26 from both sides:
(26 - 26) - 8 w = 21 - 26
26 - 26 = 0:
-8 w = 21 - 26
21 - 26 = -5:
-8 w = -5
Divide both sides of -8 w = -5 by -8:
(-8 w)/(-8) = (-5)/(-8)
(-8)/(-8) = 1:
w = (-5)/(-8)
Multiply numerator and denominator of (-5)/(-8) by -1:
Answer: w = 5/8
