Solve the equation 6(3x + 4) = 4x − 4.

x equals negative ten sevenths
x equals negative four sevenths
x = −2
x = 2

x = - 2

Step-by-step explanation:

Given

6(3x + 4) = 4x - 4 ← distribute parenthesis on left side

18x + 24 = 4x - 4 ( subtract 4x from both sides )

14x + 24 = - 4 ( subtract 24 from both sides )

14x = - 28 ( divide both sides by 14 )

x = - 2

x = -2

Step-by-step explanation:

6(3x + 4) = 4x − 4

Distribute:

18x + 24 = 4x - 4

18x - 4x + 24 = -4

14x + 24 = -4

14x = -4 - 24

14x = -28

x = -28 / 14

x = -2

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!
