 Question 85331: Solve. 10(–x – 7) + 20 = –5(2x + 4) Here is what I ahve 10(-7 + -1x) + 20 = -5(2x + 4) (-7 * 10 + -1x * 10) + 20 = -5(2x + 4) (-70 + -10x) + 20 = -5(2x + 4) -70 + 20 + -10x = -5(2x + 4) -70 + 20 = -50 -50 + -10x = -5(2x + 4) -50 + -10x = -5(4 + 2x) -50 + -10x = (4 * -5 + 2x * -5) -50 + -10x = (-20 + -10x) -50 + -10x + 10x = -20 + -10x + 10x -10x + 10x = 0 -50 + 0 = -20 + -10x + 10x -50 = -20 + -10x + 10x -10x + 10x = 0 -50 = -20 + 0 -50 = -20 Click here to see answer by jim_thompson5910(28595)

 Question 85398: Hello and thank you, My question is..... can you give me step by step instructions on equations with two variables now for instance I can solve a question like this x=2y when x=0 that is easy. My question is when the questions are like this.... 2x +2y when y=2 what is throwing me off is the fact that it has a number in front of the letter in both? am I making any sense? I have searched the internet and connot find any sample question that have "when x=2" or when x=0 (not necessarily having to be those particular numbers) can you help? I hope my question didnt confuse you? here is a sample question that if you solve for me I can plug into to solve the rest of my home work Sample question: 2x+2y=4 When x=4 PLEASE HELP ME IM SOOO CONFUSED Thank you Renee Click here to see answer by bucky(2189)
