Y-32=-5/4(x-32) math

Mathematics
1 answer:
AleksandrR [38]4 years ago
5 0

Answer:

x=3 y=4

Step-by-step explanation:

x+y=7; x + 2y =11

step: solve x + y = 7 for x:

x + y+ -y =7 + -y (add -y to both sides)

x = -y + 7

step: substitute -y + 7 for x in x + 2y =11:

x + 2y = 11

-y + 7 + 2y = 11

y + 7 =11(simplify both sides of the equation)

y + 7 + -7 = 11 + -7 (add -7 to both sides)

y = 4

step: substitute 4 for y in x = -y + 7:

x = -y +7

x = -4 + 7

x = 3 (simplify both sides of the equation)

John is 3 years older than Jim. Jim is 4 years less than half of Dana’s age. How old is each person if their ages add up to 167?
kogti [31]

Solution:

we are given that

John is 3 years older than Jim. Jim is 4 years less than half of Dana’s age.

Let the age of Jim be x years then we can say

Age of John=x+3

If diana Age is D then

x=D/2-4

It can be re-wriiten as

Diana age D=2x+8

Given that  their ages add up to 167

x+x+3+2x+8=167\\
\\
4x+11=167\\
\\
4x=167-11\\
\\
4x=156\\
\\
x=39\\

Hence jim is 39 nyears old, John is 39+3=42 years old. and Diana is 2*39+8=78+8=86 years old.
