Question

(3/7+1/3y)×21=19 Плизз

Answer 1

3\7+1\3y=19:21
1\3y=19\21-3\7
1\3y=10\21
y=10\21: 1\3
y=одна целая 3\7

Answer 2

To solve this equation, we can use the following steps:

1. Simplify the left-hand side of the equation by multiplying the fractions and combining like terms:

(3/7 + 1/3y) × 21 = (9/21 + 7/21y) × 21 = 9 + 7y

2. Set the simplified left-hand side equal to the right-hand side and solve for y:

9 + 7y = 19 7y = 10 y = 10/7

Therefore, the solution to the equation (3/7 + 1/3y) × 21 = 19 is y = 10/7.
