Answer:
w=−5
Step-by-step explanation:
Step 1: Subtract 3w from both sides.
7w+5−3w=3w−15−3w
4w+5=−15
Step 2: Subtract 5 from both sides.
4w+5−5=−15−5
4w=−20
Step 3: Divide both sides by 4.
4w4=−204
Answer: w=−5
Hope this helps.
Answer:
w =-5
Step-by-step explanation:
Group the variables and constant on each side
remember that the signs will change while switching the places.
7w-3w=-15-5
4w=-20
divide the coefficient to keep only the variable and find its value
4÷4w= -20÷4
w= -5
therefore w is -5
