Question

Solve.

7x = 2x – 35



Solve.
1/5(25-5a)=4-a

Answer 1

7x = 2x – 35
variable to one side constant to the other
whatever you do to one side of an equation also do to the other to keep the balance
7x -2x = -35 and simplify if possible
5x = -35
divide by the coefficient of the variable (to get 1* variable)
5x/5 = -35/5
x = -7
check
left side 7(-7)= -49
right side 2(-7)-35 = -7-35 = -49
left = right therefore yes x = -7

Answer 2

now try the other one
first multiply every term by the lowest common multiple to get rid of the fraction

Answer 3

125-25a=4-a right?

Answer 4

no every term is multiplied when you get rid of fractions
actually you can factor out 5 on the left side

Answer 5

I'm horrible with fractions :/
