Question

What is the solution of 7x + 14 - 3x = 30? O A. 4 o B. -11

Answer 1

X = 4

7(4)+14-3(4)=30

7(-11)+14-3(-11)=-30

So, 4 is the answer because when substituted for X, it gives you 30.

Answer 2

Answer:

A=4

Step-by-step explanation:

7x+14-3x=30

collect the like terms 7x-3x=4x than

it's gonna be 4x+14=30 and move constant to the right side and change its sign 4x=30-14 and subtract 30-14=16

4x=16 and divide both sides of the equation by 4

it's gonna be x=4
