Y = x + 4
2x - 3y = -13

y = x + 42x -3y = -13

(1,5)

Step-by-step explanation:

2x-3(x+4)=-13        y=1+4

2x-3x-12=-13          y=5

-x-12=-13

+12

-x=-1/-1

x=1

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

using pemdas, (order of operations) you'll see the answer is 24.
