Another math problem i cant solve.

 x = 7, y = -3

Step-by-step explanation:

3y = 26 - 5x     --> added 5x to both sides to get:  5x + 3y = 26

Elimination method (I am going to eliminate "x":

5x + 3y = 26   →    6(5x + 3y = 26)    →     30x + 18y = 156

6x + 7y = 21    →   -5(6x + 7y = 21)     →   -30x - 35y = -105

                                                                          -17y  =   51

                                                                        ÷-17      ÷-17

                                                                              y =   -3

Now, input y = -3 into one of the original equations to solve for "x":

    3y = 26 - 5x

 3(-3) = 26 - 5x

     -9 = 26 - 5x

-9 -26 = -5x

    -35 = -5x

      7  =  x

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
