Ok to start this problem you must list two numbers that add to 14
7 and 7
9 and 5
10 and 4
6 and 8
those are the numbers that we will use for now..
Now multiply each pair of numbers and see which one equals 45
7 * 7 = 49, no
9 * 5 = 45, YES
10 * 4 = 40, No
6 * 8 = 48, No
The numbers discovered are 9 and 5
Answer:
x= 1
y= -3
Step-by-step explanation:
multiply them to get common factor for y or x:
3(7y+10x=-11)
10(4y-3x=-15)
21y+30x=-33
40y-30x=-150 <em>x's cancel out so solve for y</em>
61y = -183
/61 /61
y = -3 <em> insert y into either equation and solve for x</em>
<em />
<em>4(-3) -3x=-15</em>
<em>x = 1</em>
