1 plus 1 plus 1 plus 1 equals 1 times 4. 1 times 4 equals 4. 4 minus 4 equals 0. 0
22 = 4
x = y = 0 ?
That would still be 4. If it were times 0 it would be 0.
4+4=8+0=8+1=9+1=10+0=10+1=11 It equals 11. You're welcome.
1 plus 1 plus 1 plus 1 equals 1 times 4. 1 times 4 equals 4. 4 minus 4 equals 0. 0
22 = 4
x = y = 0 ?
4(x + 1) = 0.
That would still be 4. If it were times 0 it would be 0.
x = 0
x = 0 and y = 4
4+4=8+0=8+1=9+1=10+0=10+1=11 It equals 11. You're welcome.

well it equals 4 any way you put
5n+4=0 5n=-4 n= -4/5
x^2/x +2=4/x +2 (x^2/x)-(4/x)=0 (x^2-4)/x=0 x^2-4=0 (x+2)(x-2)=0 x=±2
