Answer:
the twins will always have the same age
Step-by-step explanation:
the equation for jasmine's age is 2(3x+6), while the equation for james's age is 3(2x+4)
2(3x+6) = 2*3x + 2*6 = 6x + 12
3(2x+4) = 3*2x + 3*4 = 6x + 12
since both have the same equation, both will be the same age when you plug in the same x value
Answer:
Yes, and if you need extra help try yay math
Step-by-step explanation:
Y = 2
y = 4x - 10
2 = 4x - 10
2 + 10 = 4x
12 = 4x
12/4 = x
3 = x
solution is : (3,2)
Answer:
15 and 1
Step-by-step explanation:
x and y are two numbers.
Two equations:
x · y = 15
x + y = 16
Rearrange one of the equations (I'll rearrange the sum equation):
x + y = 16
x = 16 - y
Substitute that to the other equation and solve for y:
x · y = 15
(16 - y) · y = 15
16 - y · y = 15
16 - y² = 15
-y² = 15 - 16
-y² = -1
y² = 1
y = √1
y = 1
Now substitute that to any of the equation and solve for x (in here, I'll choose the multiplication one):
x · y = 15
x · 1 = 15
x = 15
Now verify:
15 · 1 = 15
15 + 1 = 16
This is correct
