X + 5y = 28

2x + 3y = 21

for first one  x=28-5y

second one x=-3/29(y-7)

Step-by-step explanation:

im sure its right

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.
