x = 3
2x + 7 =....
2 (3) + 7 = 6 + 7 = 13
this is my answer how about my answer ?
The equation in the form 0 = ax^2 + bx + c is:
0 = x^2 + x + 2
The discriminant = b^2 - 4ac
Discriminant = (1)^2 - 4(1)(2)
= 1 - 8
= -7
2x + 9 = 35
We subtract 9 in both sides:
2x + 9 - 9 = 35 - 9
2x = 26
We then divide 2 in both sides:
x = 13
