4(5+2)+1.3=3(y+2.1)

Solution for 4(5+2)+1.3=3(y+2.1) equation:

Simplifying
4(5 + 2) + 1.3 = 3(y + 2.1)

Combine like terms: 5 + 2 = 7
4(7) + 1.3 = 3(y + 2.1)

Multiply 4 * 7
28 + 1.3 = 3(y + 2.1)

Combine like terms: 28 + 1.3 = 29.3
29.3 = 3(y + 2.1)

Reorder the terms:
29.3 = 3(2.1 + y)
29.3 = (2.1 * 3 + y * 3)
29.3 = (6.3 + 3y)

Solving
29.3 = 6.3 + 3y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-3y' to each side of the equation.
29.3 + -3y = 6.3 + 3y + -3y

Combine like terms: 3y + -3y = 0
29.3 + -3y = 6.3 + 0
29.3 + -3y = 6.3

Add '-29.3' to each side of the equation.
29.3 + -29.3 + -3y = 6.3 + -29.3

Combine like terms: 29.3 + -29.3 = 0.0
0.0 + -3y = 6.3 + -29.3
-3y = 6.3 + -29.3

Combine like terms: 6.3 + -29.3 = -23
-3y = -23

Divide each side by '-3'.
y = 7.666666667

Simplifying
y = 7.666666667
