Answer: -6 = x
Step-by-step explanation: Start by distributing through the parentheses
on each side of the equation to get 5x - 40 = 7x - 28.
Now move your x's to the right and
numbers to the right and you get -12 = 2x.
Divide both sides by 2 and -6 = x
Answer:
-40=a
Step-by-step explanation:
( a-5)/(a+4) = 5/4
Multiply by (a+4) on each side
( a-5)/(a+4) * (a+4) = 5/4 (a+4)
a-5 = 5/4 (a+4)
Multiply by 4 on each side to clear the fractions
4(a-5) = 5/4*4 (a+4)
4(a-5) = 5 (a+4)
Distribute
4a -20 =5a +20
Subtract 4a from each side
4a -4a -20 = 5a-4a +20
-20 =a+20
Subtract 20 from each side
-20-20 =a+20-20
-40=a
