Find the solution of this system of equations. Separate the x- and y-values with a comma.
X+10y=-18
X-y=4

x = 2, y = -2

Step-by-step explanation:

Subtracting the 2 equations:

(x+10y)-(x-y) = -18-4

x + 10y - x + y = -22

11y = -22

y = -2

Substituting the y-value into 'x-y=4':

x + 2 = 4

x = 2

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

happy to
