Solve each given equation & show your work. tell whether it has one solution (something like x=18), an infinite number of solutions (such as when any value can be used for x, and the equation is true), or no solution (no x value will work). 25 - 4x = 15 - 3x + 10

Step 1: Simplify both sides of the equation.

25−4x=15−3x+10

25+−4x=15+−3x+10

−4x+25=(−3x)+(15+10)(Combine Like Terms)

−4x+25=−3x+25

−4x+25=−3x+25

Step 2: Add 3x to both sides.

−4x+25+3x=−3x+25+3x

−x+25=25

Step 3: Subtract 25 from both sides.

−x+25−25=25−25

−x=0

Step 4: Divide both sides by -1.

−x /−1  =  0 /−1

answer is 0.

X = 0.

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

the answer is 31.27mph
