if the following system of equations was written as a matrix equation in the form AX=C, and matrix A was expressed in the form a=[a c] [b d] find the value of a-b+c+d. 4x2y=7 5x-6y=9

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

answer: i don't understand it

step-by-step explanation: sorry
