Question

What is the solution to this equation? 4x+10+3x=40-3x

A. x=3
B. x=25/2
C. x=3
D. x=15/2

Answer 1

Answer:

A. x=3

Step-by-step explanation:

Solve for x:

4x+10+3x=40-3x

• combine like terms

7x+10=40-3x

+3x           +3x

10x+10=40

     -10   -10

10x=30

/10   /10

x=3

Answer 2

The solution to this equation 4x+10+3x=40-3x  is x=3

Explanation:

Given the equation 4x+10+3x=40-3x

Now we will solve both the left hand side and right hand side of the of the above equation

4x+3x+10=40-3x

7x+10=40-3x

Grouping the like terms one side,

$7x+3x=40-30$

$10x=30$

$x=\frac{30}{10}$

x=3

So, the value of x is 3 which satisfy the above equation which is given in the question.
