Answer:
1) x = 2.5
b) y = 12.9
c) z = 12
d) 2.75 = w or 2 = w
e) t = 4
Step-by-step explanation:
a)
2x = 5
divide both sides of the equation by 2
2x/2 = 5/2
x = 5/2
x = 2.5
b)
y + 1.8 = 14.7
subtract 1.8 from both sides of the equation
y + 1.8 - 1.8 = 14.7 - 1.8
y = 14.7 - 1.8
y = 12.9
c)
6 = 1/2z
divide both sides by 1/2 or multiply both sides by 2
6*2 = 1/2z * 2
6*2 = z
12 = z
d)
3.25 = 0.5 + w
subtract 0.5 from both sides of the equation
3.25 - 0.5 = 0.5 + 2 - 0.5
3.25 - 0.5 = w
2.75 = w
or
2 = w
e)
2.5t = 10
t = 10/2.5
t = 4
