4. How many real-number solutions does the equation have?
x^2 + 7x - 5 = 0

a. One solution
b. Two solutions
c. No solutions
d. Infinitely many solutions

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
