Best Answer

To simplify the expression 2x + 3y + 4x + 9y, you first combine like terms. Adding the coefficients of x terms gives 2x + 4x = 6x. Similarly, adding the coefficients of y terms gives 3y + 9y = 12y. Therefore, the simplified expression is 6x + 12y.

2x + 3y + 4x + 9y = 2x + 4x + 3y + 9y = 6x + 12y

which can be simplified to 6(x + 2y)

What does 4x-3y equals 1 2x plus 3y equals 2 equal?

second equation x 2: 4x + 6y = 4 subtract first equation: 9y = 3 so y = 1/3 and x = 1/2


2x plus 3y equals 3 and 4x minus 3y equals 9. What value of y is part of the solution for this system of equations?

There are two simultaneous equations, so to solve for y, eliminate x: 1) 2x + 3y = 3 2) 4x - 3y = 9 Multiply equation (1) by 2 giving: 1) 4x + 6y = 6 2) 4x - 3y = 9 Next, subtract equation (2) from equation (1), giving: (4x - 4x) + (6y - -3y) = 6 - 9 → 9y = -3 → y = -1/3


Solve this polyinomal 5x plus 6y plus 3y-2x?

What value of b will make 2x-3y equals 5 and 9y plus bx equals 4 parallel?

2x - 3y = 5 => 3y = 2x - 5 has a gradient of 2/3 9y + bx = 4 => 9y = -bx + 4 has a gradient of -b/9 The two gradiends must be the same if the two lines are parallel: 2/3 = -b/9 so that b = -6
