x=-64/35
-6/5x+2= 21/25
Do fraction cross multiply
(-6*25=(5x+2)21
Then swap the sides (5x+2) *21 = (-6)*25
multiply(5x+2)21= -150/21
simplify
5x+2=- 50/7
subtact 2
5x+2-2=- 50/7-2
silmplify 5x=-64/7
divide by 5
5x/5=-64/7/5
simplify
x= -64/35
Solve:
-6/5x + 2 = 21/25
Steps:
Solution -6/5x + 2 = 21/25 =======> 29/30, Decimal =====> x = 0.96667
Subtract 2 from both sides:
-6/5x + 2 - 2 = 21/25 - 2
Simplify:
-6/5x = -29/25
Multiply both sides by -25:
(-6/5x )(-5) = (-29/25 )(-5)
Simplify:
6x = 29/5
Divide both sides by 6:
6x/6 = 29/5/6
Simplify:
Answer x = 29/30 Decimal: 0.96667....
