Select the best possible first step to solving the following system by first eliminating the y variable. 5x - 3y = 1 7x - 4y = 2 Choose one answer. a. Multiply the first equation by 3 and multiply the first equation by 4. b. Multiply the first equation by -3 and multiply the second equation by -4. c. Multiply the first equation by -7 and multiply the second equation by 5. d. None of the above.
OpenStudy (austinl):
None of the options given work.
OpenStudy (uri):
None of the above..We can't make them equal from the given options.
OpenStudy (littlebird):
this problem is setting you up for elimination, starting with y. This means that when you subtract the second equation from the first equation, the y variable should disappear. Each of the answer choices are supplying a way to change the equations so that when you subtract them from each other the y's cancel.
