Answer:
-1
Step-by-step explanation:
first add up all the like terms on the right:
4x + 2x + x adds up to 7x
next it should be
-7 = 7x
divide 7x to both sides and the answer should be negative 1
Answer:
x = -1
Step-by-step explanation:
This is an algebraic linear equation
-7 = 4x + 2x + x
4x + 2x + x = -7
7x = -7
Divide both sides by the coefficient of x that is, 7
x = -1
