Answer:
x=5
Step-by-step explanation:
x^2+25-10x = x^2-25
-x^2 -x^2
25-10x = -25
-25 -25
-10x = -50
x=5
lets check
(5-5)^2 = 5^2-25
0^2 = 25-25
0 = 0
203---- 100%
x-----148%
x=203*148/100=203*1.48=300.44
B)10+5(8)+2(12)=74
10+40+24=74

Answer: Lin is correct but her thinking is wrong.
Step-by-step explanation:
2x-32+4(3x-2462)=14x
First solve parentheses: 2x-32+12x-9842=14x (you distribute the 4).
Then add common factors on the same side of the equal signs:
14x-9880=14x
When solving for x you would subtract 14x giving you:
-9880=0 which would never be true.
