If the solution to the equation is x = -2, find the value of a
4x-2(x-a)= 14

x=-2

4x-2(x-a)=14

4*(-2) -2(-2-a)=14

-8+4+2a=14

-4+2a=14

2a=18

a=9

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
