Solving simultaneous equations algebraically - Working …
WebSo I have 2x squareds, and I subtract out a 1/4 x squared, so I'm going to have a 1 and 3/4 x squared. Or you could view this as 8/4 minus 1/4 is 7/4 x squared. 7/4 x squared is equal to 7. Multiply both sides times the reciprocal of 7/4, so 4/7. Multiply both sides by 4/7. And we get x squared is equal to 4.
