You use Plus as a symbol in Maths. Example, 2 Plus 2 equals 4. Or in symbols it would be 2+2=4. __________________________ Plus = + Equals = = (Equals equals =)
The answer is 21 because if 21 is divided by 3 it equals 7 plus 4 equals 11.
It would be y=-x
That equals 1/4.
x= -15, would you like me to explain, comment
It equals 4 over 9. 4/9
x over 4= 2x+3 over 15
1 and 2/5
4+1=5. Plus 4 equals 9. Plus 77685769844446473 equals 77685769844446482. Plus 3 equals 77685769844446485. Plus 8 equals 77685769844446493. Plus 1 equals 77685769844446494. Plus 9870998342523322424 equals 1064785604097768918. Plus 4 equals 1064785604097768922.
2/9+4/9=6/9, which equals 2/3
