User: Solve each equation. 4 = x2 -7

Weegy: -7 = h/5 = -h/5-7 = 0 h = -35

User: Solve each equation. Leave the answer as an improper fraction. 16x2 = 49

Weegy: 16x2 = 32 x2=49/16=16 - > x=+, - sqrt (4)

User: Which of the following shows an equivalent form of the equation t²+5t-24=0?

Weegy: If an equation of a system is equivalent with 0=k, with k not zero, then the system has no solutions. ... First I'll show the row transformations, then I'll state the method in words. ... [ 1 -4 10 24] [0 -5 10 -24 -57] r2/(-5) [1 1 -4 10 24 ] [0 1 -2 4.8 11.4] ]

5x^2 + 500 = 844.45
5x^2 = 844.45 - 500 = 344.45
x^2 = 344.45/5 = 68.89
x = ± 8.3

t² - t = 12
t² - t - 12 = 0
(t - 4)(t + 3) = 0
t - 4 = 0 or t + 3 = 0
t = 4 or t = -3
