Solution for 0.06(y-7)+0.04y=0.20y-0.03(40) equation:


Simplifying
0.06(y + -7) + 0.04y = 0.20y + -0.03(40)

Reorder the terms:
0.06(-7 + y) + 0.04y = 0.20y + -0.03(40)
(-7 * 0.06 + y * 0.06) + 0.04y = 0.20y + -0.03(40)
(-0.42 + 0.06y) + 0.04y = 0.20y + -0.03(40)

Combine like terms: 0.06y + 0.04y = 0.1y
-0.42 + 0.1y = 0.20y + -0.03(40)

Multiply -0.03 * 40
-0.42 + 0.1y = 0.20y + -1.2

Reorder the terms:
-0.42 + 0.1y = -1.2 + 0.20y

Solving
-0.42 + 0.1y = -1.2 + 0.20y

Solving for variable 'y'.

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

Add '-0.20y' to each side of the equation.
-0.42 + 0.1y + -0.20y = -1.2 + 0.20y + -0.20y

Combine like terms: 0.1y + -0.20y = -0.1y
-0.42 + -0.1y = -1.2 + 0.20y + -0.20y

Combine like terms: 0.20y + -0.20y = 0.00
-0.42 + -0.1y = -1.2 + 0.00
-0.42 + -0.1y = -1.2

Add '0.42' to each side of the equation.
-0.42 + 0.42 + -0.1y = -1.2 + 0.42

Combine like terms: -0.42 + 0.42 = 0.00
0.00 + -0.1y = -1.2 + 0.42
-0.1y = -1.2 + 0.42

Combine like terms: -1.2 + 0.42 = -0.78
-0.1y = -0.78

Divide each side by '-0.1'.
y = 7.8

Simplifying
y = 7.8
