0.16(15x-2) =0.4x+7
Answers
Answer:
Step-by-step explanation:
0.80x - 0.32 = 0.4x + 7
0.80x - 0.4x = 0.32 +7
0.40x = 7.32
x = 7.32/0.40 = 183
x = 183

Simplifying
0.16(5x + -2) = 0.4x + 7
Reorder the terms:
0.16(-2 + 5x) = 0.4x + 7
(-2 * 0.16 + 5x * 0.16) = 0.4x + 7
(-0.32 + 0.8x) = 0.4x + 7
Reorder the terms:
-0.32 + 0.8x = 7 + 0.4x
Solving
-0.32 + 0.8x = 7 + 0.4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-0.4x' to each side of the equation.
-0.32 + 0.8x + -0.4x = 7 + 0.4x + -0.4x
Combine like terms: 0.8x + -0.4x = 0.4x
-0.32 + 0.4x = 7 + 0.4x + -0.4x
Combine like terms: 0.4x + -0.4x = 0.0
-0.32 + 0.4x = 7 + 0.0
-0.32 + 0.4x = 7
Add '0.32' to each side of the equation.
-0.32 + 0.32 + 0.4x = 7 + 0.32
Combine like terms: -0.32 + 0.32 = 0.00
0.00 + 0.4x = 7 + 0.32
0.4x = 7 + 0.32
Combine like terms: 7 + 0.32 = 7.32
0.4x = 7.32
Divide each side by '0.4'.
x = 18.3
Simplifying
x = 18.3
