The -2x should be added to the left side.
3x - 7 = -2x + 8
3x + 2x = 8 + 7

Answer:
Step-by-step explanation:
x = 0.6 m
F = 78 N
Let k be the spring constant.
F = k x
78 = 0.6 k
k = 130 N/m
(a)
x = 5.5 m
W = 0.5 kx²
W = 0.5 x 130 x 5.5 x 5.5
W = 7865 J
(B) x = 1.5 m
W = 0.5 kx²
W = 0.5 x 130 x 1.5 x 1.5
W = 146.25 J
Answer:-18x+42
