Collin wants to solve this system of equations. Which number can he multiply the first equation by so that when the two equations are added together, the x term is eliminated? One-half x + one-fourth y = 5 2 x + three-eighths y = 5 –4 –2 2

-4

Step-by-step explanation:

The given equations are as follows:

The coefficient of x in the second equation is 2.

So in order to eliminate x we need to multiply the first equation by a value so that the coefficient of x becomes -2.

Since the coefficient of x in the first equation is \[\frac{3}{8}\], it needs to be multiplied by -4.

So the required multiplier for the first equation is -4

24/56=hx^7

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
