Let x represent the larger number.
Let y represent the smaller number.
x-y=4 Given
3x=5y-2 Given
Now we can just substitute; let x=4+y
Substitute 4+y for x in the second equation:
3(4+y)=5y-2
12+3y=5y-2
-2y=-14
y=7
Substitute back (into BOTH equations to double check work).
x, the larger number, is 11
Answer:
True ; false ; False ; true
Step-by-step explanation:
Equation 1:
7 20 + □ = 19 20
19 / 20 - 7/20
(19 - 7) / 20
12/ 20 = 3/5
Equation 2:
□ + 3 10 = 3 15
3/5 + 3/10
(6 + 3) / 10 = 9/10
Equation 3:
1 2 + 2 3 = □
1/ 2 + 2/3
(3 + 4) / 6
7 / 6
Equation 4:
1 10 + 1 2 = □
1/10 + 1/2
(1 + 5) / 10
6 / 10 = 3/5
