Question

(5у-7)(4у-0,8)=0 Решите

Answer 1

(5у-7)(4у-0,8)=0
5у₁-7=0       у₁=1,4
4у₂-0,8=0    у₂=0,2

Answer 2

To solve the equation (5у-7)(4у-0.8) = 0, you need to find the values of у (y) that make the equation true. To do this, set each factor equal to zero and solve for у (y):

1. Set 5у - 7 = 0: Add 7 to both sides: 5у = 7 Divide both sides by 5: у = 7/5

2. Set 4у - 0.8 = 0: Add 0.8 to both sides: 4у = 0.8 Divide both sides by 4: у = 0.8/4 у = 0.2

The two solutions for у (y) are:

1. у = 7/5
2. у = 0.2
