What is the solution of 7x + 14 - 3x = 30?

O

A. 4

o

B. - 11

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

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.
