y = 3x + 2
y = 7x - 10
Answer:
x=3
y=11
Step-by-step explanation:
y = 3x + 2 equation 1
y = 7x - 10 equation 2
using equation 1 in equation 2 we have:
3x + 2 = 7x - 10
2=7x - 3x -10
2 = 4x -10
2+10 = 4x
12= 4x
12/4 = x
we have:
x= 3
using equation 1:
y = 3x + 2
y= 3(3)+2
y=9+2
y=11
Answer: There are many possibilities such as 108,180,162,126 etc.
Step-by-step explanation:
As it is under 200 the hundreds digit should be 1. And as it should be even, the ones digit should be a multiple of 2. Then finally in the tens place, there should be a number, so that when you add the hundreds digit and ones digit with that number, the sum is 9.
Hope this helps!
