x on first one=1

x on 2nd one =5

Step-by-step explanation:

b/c 1*1=1

2*1=2-1=1

b/c 5*5=25*3=75+4=79

1. 2x^2 - 1 = 1

Step 1: Divide both sides by two

Step 2: Simplify

Answer for Question 7: x = 1, x = -1

2. 3x^2 + 4 = 79

Step 1: Subtract 4 from both sides

Step 2: Simplify

Step 3: Divide both sides by 3

Step 4: Simplify

Answer for Question 8: x = 5, x = -5
