Answer: -4 = <em>w OR w = -4</em>
Step-by-step explanation: For this given equation you will have to solve for the variable w. In order to do this you must isolate the variable <em>w.</em>
Step 1: Use the distributive property: -79=7w+3(4w-1) ( 3 x 4w = 12w and 3 x -1 = -3.
Step 2: Add like terms and whole numbers: -79=7w+12w-3 ( 7w + 12w = 19w
Step 3: Use the Addition Property of Equality:3 + -79=19w-3+3 ( 3 + -79 = -76 and -3 + 3 =0
Step 4: Use the division Property of Equality: -76=19w -76 divided by 19 is -4 and 19w divided by 19 is w
Step 5: The answer: -4=w
