Find all real solutions to (x-7)^2=4

x-=sqrt53

Step-by-step explanation:

(X-7)^2=(x^2-49)

add 49 to both sides

sqrt both sides

x = 9

x = 5

In order to find the answer we need to get rid of the square so we are going to square root it like this:

(x - 7)^2 = 4

x - 7 = 2

= plus or minus 2

First add and you'll get

x = 9

And then subtract and you'll get

x = 5

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)

step-by-step explanation:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
