5 (2x + 10) = 50 What is the answer

KATRIN_1 [288]

9514 1404 393

Answer:

x = 0

Step-by-step explanation:

You can eliminate parentheses and subtract 50.

5(2x +10) = 50

10x +50 = 50 . . . . use the distributive property

10x = 0 . . . . . . . . . subtract 50 from both sides

x = 0 . . . . . . . . . . . divide by 10

Check

5(2·0 +10) = 50

5(10) = 50 . . . . true

Solve the simultaneous equations y = 4x + 1 y = 2x^2+ 7x - 1

mixer [17]

Answer:

$Given,\\y = 4x+1......(1)\\y = 2x^2+7x-1.............(2)\\Equating~equation (1)~and~(2),\\4x+1 = 2x^{2} +7x-1\\or, 2x^{2}+7x-4x-1-1=0\\or, 2x^{2} + 3x-2=0\\or, 2x^{2} +4x-x-2=0\\or, 2x(x+2)-1(x+2)=0\\or, (x+2)(2x-1)=0\\i.e. x=-2 ~or~ \frac{1}{2} \\When~x=2,~equation(1)~becomes ~y=4(-2) +1=-7\\When~x=-\frac{1}{2},~equation (1)~becomes~y=4(\frac{1}{2}) +1 = 2+1=3$

So, the required values of x are -2 and 1/2 and that of y are -7 and 3.
