We can set up a system of equations:

x + y = 12
x - y = 4

Adding these two together:

2x = 16
x = 8

Substituting 8 in the first equation:

8 + y = 12
y = 4

Hope this helps!

aleksklad [387]

Answer:

\boxed{\bold{15x+78}}

Step By Step Explanation:

Apply Rule - (-a) = a

\bold{6\left(4x+12\right)-9x-18+4\cdot \:6}

Multiply: 4 · 6 = 24

\bold{6\left(4x+12\right)-9x-18+24}

Expand \bold{6\left(4x+12\right): \ 24x+72}

= \bold{24x+72-9x-18+24}

7/8 - 1/4 - 1/2= ??
madreJ [45]

Step-by-step explanation:

We can break this up into pieces, first we do, 7/8 - 1/4, find the least common denominator which is 8, so the equation will be 7/8 - 2/8, which we can now subtract and will give us, 5/8, now that we have done that, we can do 5/8 - 1/2. Since we know that half of 8 (our denominator) is 4. Then the equation would be 5/8 - 4/8, which brings us to 1/8 as our final answer.

Cheers!
