Answer:
Step-by-step explanation:
-3w + 7 = -14
subtract 7 from both sides
-3w + 7 - 7 = - 14 -7
-3w = -21
divide both sides by (-3)
-3w/-3 = -21/-3
w = 7
In short:
-3w + 7 = -14
-3w = -14 - 7
-3w = -21
w = -21/-3
w = 7
There are many solutions. infinite solutions at that. when you solve it it equals itself 2.5w+21= 2.5w+21 so that means all numbers would work as a solution.
Answer:
Step-by-step explanation:
6=42/j multiply both sides by j
6j=42 divide both sides by 6
j=7
Collecting like terms is to simplify terms in expressions in which the variables are the same.
Rearranging is to change the position for example changing the place of the = sign to change the meaning of the equation.
Solving equations is to find the solution of the equation
