3. Solve using substitution.<br> x - y = 4<br> 3x - 2y = -5

Vedmedyk [2.9K]

<u>Given</u>:

The system of linear equations are $x-y=4$ and $3x-2y=-5$

We need to determine the solution to the system of equations using substitution method.

<u>Solution</u>:

The solution can be determined using the substitution method.

Let us substitute $x=4+y$ in the equation $3x-2y=-5$

Thus, we have;

$3(4+y)-2y=-5$

$12+3y-2y=-5$

$12+y=-5$

$y=-17$

Thus, the value of y is -17.

Substituting $y=-17$ in the equation $x-y=4$ , we get;

$x+17=4$

$x=-13$

Thus, the value of x is -13.

Hence, the solution to the system of equations is (-13,-17)

You would need to fill in the cut out part of the shape. Find the area of the whole shape minus the area of the cut out shape.

Area of the bigger shape :6*9 =54cm squared

Area of the cut out shape:4*4=20cm squared

<h3>Area of the whole shape is 54 - 20 = 34cm squared</h3>
