Answer:
x = -6
Step-by-step explanation:
-7x+16=58
Subtract 16 from each side
-7x+16-16=58-16
-7x = 42
Divide by -7
-7x/-7 = 42/-7
x = -6
Rearrange the equation to standard form of a quadratic equation (ax^2+bx+c=0) by switching sides: 5x^2+2x-12=0. Now, use the quadratic equation formula to solve. You should come out with x_1=sqrt61-1/5 and x_2=-1+sqrt61/5. Thus, your answer is B, or two solutions.
