The solution to the system of equation is (0, 2). The equation has only one solution.

Step-by-step explanation:

Given the system of equations

y= x + 2 1

2y = x + 4 ... 2

Substitute equation 1 into 2;

From 2; 2y = x+4

2(x+2) = x+4

2x+4 = x+4

2x - x = 4-4

x = 0

Substitute x = 0 into 1;

From 1; y = x+2

y = 0+2

y = 2

Hence the solution to the system of equation is (0, 2). The equation has only one solution.

the perimeter is increased by a factor of 2
