X=4.2
For the second equation, y=4x-25. Then you plug that into the first equation, which would form: 2x+2(4x-25)=17. Simplify. 2x+8x-25=17. 10x=42. x=4.2
Well when you simplify it you get this,
0=-24,
Do what’s inside the parentheses first
3-3 is 0, 3•0 is 0
2•positive 3 is 6
6- -30 is -24
So you have 0=-24
Or just -24 :)
