Solve the equation. 2x − 3 + 4x = 21 a. x = −12 b. x = −6 c. x = 4 d. x = 6

Step 1 ) Add like terms.

2x − 3 + 4x = 21

6x - 3 = 21

Step 2 ) Add 3 to both sides.

6x - 3 = 21

6x - 3 + 3 = 21 + 3

6x = 24

Step 3 ) Divide both sides by 6.

6x = 24

x = 4

Since it cannot be simplified any farther, x in 2x − 3 + 4x = 21 is...

C ) x = 4

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
