How do you solve 8x plus 4 equals 3x plus 8?

Answer 1

8X + 4 = 3X + 8

subtract 3X from both sides of equation

5X + 4 = 8

subtract 4 from both sides equation

5X = 4

divide both sides integers by 5

X = 4/5

-------------------check in original equation

8(4/5) + 4 = 3(4/5) + 8

32/5 + 4 = 12/5 + 8

now, 4 = 20/5 and 8 = 40/5, so

32/5 + 20/5 = 12/5 + 40/5

52/5 = 52/5
