Answer:
x = 55/4.
Step-by-step explanation:
4/5x - 8 = 3
(4/5) x - 8 = 3
Add 8 to both sides:
(4/5)x = 11
Next, to isolate x, we multiply both sides by 5/4:
(5/4)(4/5)x = 11 * 5/4
1x = 55/4.
Rather than just multiplying 5/4 with 8, she has to multiply it with 3 + 8. She could put parentheses around the 3 + 8, according to PEMDAS, this would mean that the parenthesis must be solved before multiplication. The correct answer would be:
4/5x = 3 + 8
x = (3 + 8)5/4
x = 11 x 5/4
x = 55/4 or 13.75
147
180-33=147
x8+12
x+1
1/2 plus 1/3 is 5/6.
