All you should have to do is take 180-95 to get 85 for x & then take 85+45= 130 - 180 = 50.
x=85 & y=50
The answer should be 0.5x^4+12.5
You have to solve the two equations by eliminating x or y
<span>2x+5y=10 </span>
<span>x-3y=1 </span>
<span>Multiply all terms of second equation by two and subtract from first equation, thus eliminating x </span>
<span>2x+5y-2x+6y=10-2 </span>
<span>11y=8 </span>
<span>y=8/11 </span>
<span>x=3y+1=3* 8/11+1=25/11 </span>
<span>11x+11y= 11*25/11+ 11*8/11 </span>
<span>= 25+8=33</span>
3x+250-100×2x = 24.5x to 2nd power.
Got this same question earlier in the year.
