Step-by-step explanation:

13x+ 7y=135

13x+ 11y= 175

by subtraction

4y=40

y=10

substituting the value of y in any of the above equation

13x+7×10= 135

13x+70=135

13x=135-70

13x=65

x=65/13

x=5

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
