Step-by-step explanation:
In matrix multiplication, the number of columns in the 1st matrix is equal to the number of rows in the 2nd matrix.
Multiply each element of the 1st row of the 1st matrix by the corresponding element of the 1st column of the 2nd matrix. Then add these products to obtain the element in the 1st row, 1st column of the product matrix.
The remaining elements of the product matrix are found in the same way.
Simplify each element by multiplying the individual terms.
Now, sum each element of the matrix.
Well to set up a substitution equation, you need to make sure you have something you can sub in that's identical in both equations.
we have
3x-y=5
x-4y=-24
what's in common? x and y.
take one of the equations and solve for x or y like so (i'm doing y)
3x-5=y
then substitute the whole 3x-5 equation for y in the second equation. it is quite similar to how you would normally substitute a number like if y=5, then you substitute 5 for y in the second equation, but instead the "5" is an equation "3x-5"
x-4y=-24
x-4(3x-5) = -24
Now that you got it set up, you just need to solve for x and once you got x value, plug the x value in the original equations to find y.
