Treat the matrices on the right side of each equation like you would a constant.
Let 2<em>X</em> + <em>Y</em> = <em>A</em> and 3<em>X</em> - 4<em>Y</em> = <em>B</em>.
Then you can eliminate <em>Y</em> by taking the sum
4<em>A</em> + <em>B</em> = 4 (2<em>X</em> + <em>Y</em>) + (3<em>X</em> - 4<em>Y</em>) = 11<em>X</em>
==> <em>X</em> = (4<em>A</em> + <em>B</em>)/11
Similarly, you can eliminate <em>X</em> by using
-3<em>A</em> + 2<em>B</em> = -3 (2<em>X</em> + <em>Y</em>) + 2 (3<em>X</em> - 4<em>Y</em>) = -11<em>Y</em>
==> <em>Y</em> = (3<em>A</em> - 2<em>B</em>)/11
It follows that

Similarly, you would find

You can solve the second system in the same fashion. You would end up with

He needs 1080 I believe so 38
because 1042 divided for 45 museums would be 23.15 meaning it wouldn't be the same amount for all
but if they get 38 pictures (1080) and divide it between the 45 museums it would be an even number of 24
so the answer is 38 more pictures
Answer:
507
Step-by-step explanation:
For the Algebraic Expression,
let the two numbers be X and y
lets assume x = 217
From the question,
217 + y = 724
y = 724-217
y = 507
Therefore, the other number is 507
V+4 3/4=5 2/5
v+4.75=5.4
v=0.65. Hope it help!
