Solve, using linear combination. <br> 3x + y = 4<br> 2x + y = 4

nataly862011 [7]

X would be 0 while Y would be 4

3x+y=4
-(2x+y=4)
----------------
x=0

Plug in x to any of those two equations in their original form

3(0)+y=4

0 + y = 4

y = 4

weqwewe [10]

Answer:

Step-by-step explanation:

A= length x width

A =300

Solve the equation Square root of x minus 5+ 7 = 11 for the variable. Show each step of your solution process. (10 points)

Murrr4er [49]

$\sqrt{x - 5} + 7 = 11$

$(\sqrt{x-5}) ^{2} = (4)^{2}$

|x - 5| = 16

x - 5 = +/- 16

x - 5 = 16 or x - 5 = -16

x = 21 or x = -11

Answer: x = {21, -11}
