Question

Solve and check the linear equation.
-0.40 ( 30 ) + 0.70 x = 0.60 ( 30 + x )
A) { 50} 
B) { 30 }
C) { 60 }
D) { 70 }

Quizplus · Accepted Answer

First, simplify both sides: 0.40 * 30 + 0.70x = 0.60 * 30 + 0.60x. This simplifies to 12 + 0.70x = 18 + 0.60x. Subtract 0.60x from both sides to get 0.10x = 6. Divide by 0.10 to solve for x, giving x = 60.
