Hi there!
-5(4n - 2.4) + 2(1.3 + 6n) = -5.4
Distribute the coefficients outside of the parenthesis:
-5(4n) - 5(-2.4) + 2(1.3) + 2(6n) = -5.4
-20n + 12 + 2.6 + 12n = -5.4
Combine like terms:
-8n + 14.6 = -5.4
Subtract 14.6 from both sides:
-8n = -20
Divide both sides by -8:
-8n/(-8) = -20/(-8)
n = 2.5
Answer:
Step-by-step explanation:
distribute
combine terms
subtract 14.6 from both sides
divide by -8
3(x-5)-4(x+3)
Multiply the first bracket by 3
(3)(x)=3x
(3)(-5)=-15
(-4)(x)=-4x
(-4)(3)=-12
3x-15-4x-12
3x-4x-15-12 ( combine like terms)
Answer: -x-27
