Answer:
0
Step-by-step explanation:
If the line goes straight it has no slope
In this case you equation should be just
X=2
2x2+5x=12, 2x+5x=7x, 12+2=14, 7x/7=14/7, x=2
Answer:
x=4.375
Step-by-step explanation:
-3(2x-7)+5=2x-9
-6x+21+5=2x-9
-6x+26=2x-9
-6x-2x+26=2x-2x-9
-8x+26=-9
-8x+26-26=-9-26
-8x=-35
-8x/-8=-35/-8
x=4.375
