WebSimultaneous equations. The number of variables and the number of equations is the same: 3a + 2b = 18 8a + 2c = 14: Non- simultaneous equation. There are 3 variables, but there are only 2 equations. 6h + 4i +3j = 8 4h + 7i +j = −2 2h – i = 3: Simultaneous equations. The number of variables and the number of equations are the same. WebThen do the same for the denominator on the right and the numerator on the left. These new expressions will be equal to each other. For your example, it will look like: (x-9) (-2)= (x) (7) Distribute/multiply to get: -2x + 18 = 7x. Add 2x to both sides to gather your variables: 18 = 9x. Divide both sides by 9.
