Let's solve step by step:
320 - (4b + 120) / 5 = 40 * 6320 - (4b + 120) / 5 = 240Multiplying both sides by 5 to get rid of the denominator:5(320) - 4b - 120 = 12001600 - 4b - 120 = 12001480 - 4b = 1200Subtract 1480 from both sides:-4b = -280Divide by -4 to solve for b:b = 70
Therefore, the value of b is 70.
Let's solve step by step:
320 - (4b + 120) / 5 = 40 * 6
320 - (4b + 120) / 5 = 240
Multiplying both sides by 5 to get rid of the denominator:
5(320) - 4b - 120 = 1200
1600 - 4b - 120 = 1200
1480 - 4b = 1200
Subtract 1480 from both sides:
-4b = -280
Divide by -4 to solve for b:
b = 70
Therefore, the value of b is 70.
