2. Solve the system of equations by substitution.
y = x - 5
y=-x+1

x=3

Step-by-step explanation:

x - 5 =-x+1

+5       +5

x=-x+6

+x   +x

2x=6

/2   /2

x=3

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
