Question

what is:  x + 3 -    2x -1  = 4

                 5            3

               

Answer 1

X= -46/7

Explanation:

step1: left part times 15 is 3(X+3)-5(2X-1)

step2: right part times 15 is 60

step3: 3(X+3)-5(2X-1)=60

step4: 3X+9-10X+5=60

step5: -7X+14=60

step6: -7X=46

step7: X= -46/7

Answer 2

(x + 3)/5 - (2x - 1)/3 = 4 / * 15

3(x + 3) - 5(2x - 1) = 15 * 4

3x + 9 - 10x + 5 = 60

7x = 60 - 9 - 5

7x = 46 / : 7

x = 6 4/7
