Answer:
b = (-3)/2
Step-by-step explanation:
Solve for b:
(-10 b)/3 = 5
Multiply both sides of (-10 b)/3 = 5 by -3/10:
(-3 (-10) b)/(10×3) = (-3)/10×5
(-3)/10×(-10)/3 = (-3 (-10))/(10×3):
(-3 (-10))/(10×3) b = (-3)/10×5
(-3)/10×5 = (-3×5)/10:
(-3 (-10) b)/(10×3) = (-3×5)/10
(-10)/10 = (10 (-1))/10 = -1:
(-3-1 b)/3 = (-3×5)/10
(-3)/3 = (3 (-1))/3 = -1:
--1 b = (-3×5)/10
(-1)^2 = 1:
b = (-3×5)/10
5/10 = 5/(5×2) = 1/2:
Answer: b = (-3)/2
-3_1/3(b) = 5
I assume you mean -3_1/3 and not
-31/3.
(-10b/3) = 5
Multiply both sides by 3 to clear the fraction.
-10b = 15
b = -15/10
Reduce.
b = -3/2
