Solve the equation.

2x − 3 + 4x = 21

x = 4

Step-by-step explanation:

2x - 3 + 4x = 21

First, combine like terms

6x - 3 = 21

Now, add 3 to both sides of the equation

6x = 24

Finally, divide both sides by 6

x = 4

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
