Answer:
x = ±2
Step-by-step explanation:
3x ^2 -4 = 8
Add 4 to each side
3x ^2 -4+4 = 8+4
3x^2 =12
Divide each side by 3
3x^2 =12
3x^2/3 = 12/3
x^2 = 4
Take the square root of each side
sqrt(x^2) = ±sqrt(4)
x = ±2

Answer:
0.4
step-by-step explanation
5x times 3 = 7 times 2x-4

2.5x times 3 = 7-4
then, divide both sides by three
2.5x = 1
lastly, divide both sides by 2.5
x = 0.4
