Question

Five less than twice a number is equal to one half the difference of three times the number and 13. Find the number

Answer 1

Answer: x = -23

Step-by-step explanation:

2x - 5 = 1/2(3x - 13)   multiple 1/2 to 3 & 13

2x - 5 = 1. 5x - 6.5    subtract 1.5x to both sides

0.5x - 5 = -6.5    add 5 to both sides

0.5x = -11.5       divid 0.5

x = -23
