Question

Solve the equation: 3x+(x+40)=60

a) 5
b) 10
c) 15
d) 20

Answer 1

To solve the equation, combine like terms, isolate the variable, and perform the appropriate operations. The correct answer is (a) 5.

Step-by-step explanation:

To solve the equation 3x+(x+40)=60, you need to simplify the expression and isolate the variable.

Begin by combining like terms: 3x + x + 40 = 60.

This simplifies to 4x + 40 = 60.

Next, subtract 40 from both sides of the equation to get 4x = 20.

Finally, divide both sides by 4 to solve for x. x = 5, so the correct answer is (a).
