Answer:x=7
Step-by-step explanation: Set up 3x-1 equal to 20
Then do your usual distributing.
What do you need to solve for?
X=r-4/7-s
S=-r/x+4/x+7
R=-sx+7x+4
(8 x 320)^1/3
(2560)^1/3
(64*40)^1/3
64^1/3 *40^1/3
4 * (8^1/3) * 5^1/3
4 * 2 * 5^1/3
8 *5^1/3
None of your choices are written correctly
Answer:
See below.
Step-by-step explanation:
2( x+3) = 5(x-4)
2x + 6 = 5x - 20
2x - 5x = -20 - 6
-3x = -26
x = 8
