Question 1
What value of v makes the
equation true?
5(5 + 5v) =-29 + 7v

Answer 1

v = - 3

Explanation:

Given

5(5 + 5v) = - 29 + 7v ← distribute parenthesis on left side

25 + 25v = - 29 + 7v ( subtract 7v from both sides )

25 + 18v = - 29 ( subtract 25 from both sides )

18v = - 54 ( divide both sides by 18 )

v = - 3

Answer 2

v = -3

Explanation:

5 (5 + 5v) = -29 + 7v

or, 25 + 25 v = -29 + 7v

or, 25 + 29 = 7v - 25 v

or, 54 = - 18v

or, v = -54/18

or, v = -3

for checking ( putting the value of v in both sides )

5( 5 + 5 (-3))= -29 + 7 (-3)

or, 5 ( 5 - 15 ) = -29 -21

or, 5 (-10) = -50

or, -50 = - 50

the equation is true
