This category refers to different types of equations: simple equations, quadratic and cubic equations, and how each one of then has to be solved.
Elimination method: 2X + 5Y =2 (-3) 3X + 8Y = 4 (2) In order to reduce the x term we need to make it have the same coefficient as the other equation, so we multiply the first one by -3 and the next one by 2 -3 x 2X -3 x 5Y= -3 x […]
Equation with brackets – Example 1 5x+3(x-6)=7x+13 After expanding the brackets the equation becomes 5x + 3x -18 = 7x +13 the numbers containing x need to be moved on one side of the “=” sign and the resto of the numbers moved on the other side. 8x-7x= 13+18 x=31 Equation with […]
Solving equations with fractions is not as complicated as it seems . Here are some examples to prove this to you: Before adding or subtracting any fraction the denominator (bottom number) needs to be the same. To get the common denominator, multiply the first fraction by 2 and the next two fractions by 9. After […]
