Respuesta :
10( 3x-4)=30-5x
30x-40 = 30 - 5x
30x +5x = 30+40
35x = 70
x = 70/35
x = 2
30x-40 = 30 - 5x
30x +5x = 30+40
35x = 70
x = 70/35
x = 2
Answer:
x=2
Step-by-step explanation:
10(3x−4)=30−5x
Step 1: Simplify both sides of the equation.
10(3x−4)=30−5x
(10)(3x)+(10)(−4)=30+−5x(Distribute)
30x+−40=30+−5x
30x−40=−5x+30
Step 2: Add 5x to both sides.
30x−40+5x=−5x+30+5x
35x−40=30
Step 3: Add 40 to both sides.
35x−40+40=30+40
35x=70
Step 4: Divide both sides by 35.
35x 70
