Which steps can be used to solve the equation a+4= - 3/a?

Multiply both sides by a

(a + 4)a = -3

Regroup terms

a(a + 4) = -3

Expand

a^2 + 4a = -3

Move all terms to one side

a^a + 4a + 3 = 0

Factor a^2 + 4a + 3

(a + 1)(a + 3) = 0

Solve for a

a = -1, -3

answer: i don't understand it

step-by-step explanation: sorry

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
