(1/2)x+(3/4)x=(4/3)x+2
solve for x
(5/4)x=(4/3)x+2
-(1/12)x=2
x= 2 * -12
x=-24
the number is -24
One-half of a number plus three-fourths of the number is 2 more than four-thirds of the number. find the number .
7 answers
Let n = the number
Express each phrase into mathematical expression:
one-half of the number is (1/2)n
three-fourths of the number is (3/4)n
2 more than four-thirds of the number is (4/3)n + 2
Therefore,
(1/2)n + (3/4)n = (4/3)n + 2
Solving, determine first the least common multiple of the denominators of all fractions in the equation. Then we can multiply it to both sides of equation to remove the fractions. The LCM of 2, 4 and 3 is 12, thus,
12 * [(1/2)n + (3/4)n] = 12 * [(4/3)n + 2]
6n + 9n = 16n + 24
Combine all terms with variable n:
15n = 16n = 24
15n - 16n = 24
-n = 24
n = -24
