Answer:

x = 5 and y = 3

Step-by-step explanation

y crosses out so you are left with

4x = 20 (divide by 4)

x = 5

plug x into either equation

Use linear combination. To solve system -2x+7y=10 X-3y=-3

Tamiku [17]

-2x + 7y = 10 ⇒ -2x + 7y = 10
 x - 3y = -3 ⇒ -2x + 6y = 6 
 y = 4
 -2x + 7(4) = 10
 -2x + 28 = 10
 -28 -28
 -2x = -18
 -2 -2
 x = 9
 (x, y) = (9, 4)

A square and a rectangle have the same perimeters.The lenght of a side of the suare is 4x-1.The lenght of the rectangle is 2x+2

Nina [5.8K]

Answer:

x=1

Step-by-step explanation:

perimeter of the square is $4(4x-1)=16x-4$

perimeter of the rectangle is $2(2x+2) + 2(2x)= 4x+4+4x=8x+4$

As rectangle and square have the same perimeter, we get that:

$16x-4=8x+4\\16x-8x=4+4\\8x=8\\x=\frac{8}{8} \\x=1$
