First collect the like terms on one side.(-3y) 2y+18=4Then solve as a normal equation.(-18) 2y=-14(÷2) y=-7

The area of a square is the length of one side squared (multiplied by itself), so for a square with side length 3, the area will be 3² or 3 x 3, which = 9. For a square with side length x, the ...

There are two easy ways to solve simultaneous equations. Substitution and elimination. In order to work with substitution we must rearrange one equation to be equal to either x or y. In this case, 2x+4y=8...

Equation 1: x+y=3Equation 2: -x+5y=-15Step 1: Check to see if any variables (x or y) can be eliminated. As there is x in equation 1 and -x in equation 2, x can be eliminated by adding the equations togeth...

Answer = 2x^3/3 + 3x^2/2 + 8x + CThis is an example of numerical integration from C1. To begin to answer this question, we can integrate each term at a time. To integrate this function, we raise the power...
