Answer:
Step-by-step explanation:
Use distributive property: a*(b +c) =a*b + a*c
-3( 6 - 1.5n) = (-3)*6 - (-3)*1.5n
= -18 + 4.5n
= - 
given
= 5 ( cross- multiply )
5(x + y) = x - y
5x + 5y = x - y ( subtract (x - y) from both sides )
4x + 6y = 0 ( subtract 6y from both sides )
4x = - 6y
= -
= - 
<span>So, what you need to take into consideration here is the order of operations. First, you have to multiply 3 by 6 and then do the rest of the question in the order it is written. So, here is how to calculate this: 3 - 3x6 +2 = 3 - 18 + 2 = -15 + 2 = -13. The correct answer is -13.Hope this helps. Let me know if you need additional help!</span><span />
Answer:
x=3
Step-by-step explanation:
-6-20=-2x+4-12x
combine like terms
-6x-20=-14x+4
+20. +20
-6x=-14x+24
+14x. -14x
8x=24
/8. /8
x=3
