Respuesta :
2(10x+15)=26
-Divide by 2 both sides
10x+15=13
-move the constant to the right
10x=13-15
- combined the right side
10x=-2
-divide by 10 to both sides
X=-1/5 or x=-.2
-Divide by 2 both sides
10x+15=13
-move the constant to the right
10x=13-15
- combined the right side
10x=-2
-divide by 10 to both sides
X=-1/5 or x=-.2
2(10x+15)=26
distribute 2
20x+30=26
subtract 30 from both sides
20x=-4
divide both sides by 20
x=-4/20
simplify
x=-1/5
