Solve for x. 13x 7 = 5x - 20 x = -3 x = -1 x = 1 x = 3

x = (-10)/43

Step-by-step explanation:

Solve for x:

91 x = 5 x - 20

Subtract 5 x from both sides:

91 x - 5 x = (5 x - 5 x) - 20

91 x - 5 x = 86 x:

86 x = (5 x - 5 x) - 20

5 x - 5 x = 0:

86 x = -20

Divide both sides of 86 x = -20 by 86:

(86 x)/86 = (-20)/86

86/86 = 1:

x = (-20)/86

The gcd of -20 and 86 is 2, so (-20)/86 = (2 (-10))/(2×43) = 2/2×(-10)/43 = (-10)/43:

x = (-10)/43

answer: i believe its b. if you sound out the sentences that sounds wrong.

i got 86 for this

hope this !
