Question

Solve the following equation. One point is given for showing steps and one point given for the correct solution.

(5x - 1)/2 + (-3x - 1)/4 = 9/2

m · Answer

2(5x-1) + (-3x - 1) = (4)(9/2)
10x - 1 + 3x - 1 = 36/2
13x - 2 = 18
13x = 20
x = 20/13

whoops mistake

m · Answer

2(5x-1) + (-3x - 1) = (4)(9/2)
10x - 2 + 3x - 1 = 36/2
13x - 3 = 18
13x = 21
x = 21/13

radar · Answer

(5x-1)2 + (-3x - 1)/4 =9/2  I would multiply all terms by 4
2(5x-1) +(-3x - 1) =18
remove parens
10x-2-3x-1=18   Now consolidate similar terms.
7x-3=18   add 3 to both sides
7x=21
x= 3     dividing both sides by 7
