Answer:
Step-by-step explanation:
15y+12x = 18 is equivalent to 5y+4x = 6
2x+3y = 12 is equivalent to -6y = 4x-24
one solution: (x,y) = (-21,18)
Hello!
So, here you want to do the distributive property.
Start on the left side of the + sign...
-3*u = -3u
-3*3 = -9
So we now we have:
(-3u + -9) + 4(4u + 2)
Now we focus on the right side of the + sign...
4*4u=16u
4*2=8
So now we have:
(-3u + -9) + (16u + 8)
Now you want to combine like terms. Start by adding terms with the same variable. So, we need to add -3u and 16u
<em>-3u + 16u =</em> 13u
Now we have:
13u + -9 + 8
Now add the constants, -9 + 8
-9 + 8 = -1
So, the simplified expression would be:
13u - 1 or 13u + -1
3/4 is greater than 1/3
4 x 3 = 12 ( so we shall choose 12 as our new denominator)
1/3 = 4/12 ( multiply 4 top and bottom to get the same denominator)
3/4 = 9/12 ( multiply 3 top and bottom to get the same denominator)
3/4 is greater than 1/3 by 5/12
hope this helps
18 = 1a + 2b
That’s the equation for it
