Solve the equation for y in terms of x.

4x + 2y = 8

y = 4 , x = 0

Step-by-step explanation:

4x + 2y =8equ{1}

make 4x subject of the formula

4x = 8- 2yequ(2)

now, substitute 4x into equ{1}

4(8-2y) + 2y = 8

32 - 8y + 2y = 8

Collect like terms

-8y + 2y = 8 - 32

-6y = -24

divide both sides by -6

y = 4

Substitute y into equ(2)

4x = 8-2(4)

4x = 8 - 8

4x = 0

divide both sides by 4

x = o

CHECK

4(0) + 2(4) =8

0 + 8 = 8

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
