Does anyone know 3x-13=4x+7

x=-20

Step-by-step explanation:

3x-13=4x+7

3x-13+13 = 4x+7+13

3x=4x+20

subtract from both sides

3x-4x = 4x+20-4x

combine like turms

-x=20

divide both sides of the equation by the same term

-x =20

-x/-1 = 20/-1

x=-20

I hope that this helped

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
