Answer:
x=-3/11
Step-by-step explanation:
(x+3)/5 +2x=0
Multiply both sides by 5 to get rid of the fraction
5*( x+3)/5 +5*2x=0*5
x+3 + 10x =0
Combine like terms
11x +3 = 0
Subtract 3 from both sides
11x+3-3 =0-3
11x = -3
Divide by 11
11x/11 = -3/11
x = -3/11
Answer:
enough to paint an area = 80 m²
Step-by-step explanation:
area = 8 x 10 = 80 m²
2 (x - 4) = -2x + 3 + 4x
2x - 8 + 2x + 3
-8 = 3 so the statment is false for any value of x
