Answer:

p=1/8 q=3/4

Step-by-step explanation:

-2p+7q=5

-6p+35q=51/2

cancel out a variable

(-5)(-2p+7q=5)

-6p+35q=51/2

10p-35q=-25

-6p+35q=51/2 =

4p=1/2

4p/4=1/2 /4

p=1/8

substitute p=1/8 into one of the equation to find q

-2p+7q=5

-2(1/8)+7q=5

-1/4+7q=5

7q=5+1/4

7q=21/4

q= 21/4 /7

q=3/4

What values of x make the equation x(squared)+9x-22=0

kkurt [141]

Answer:

$x = 2 \: \: \: \: \: or \: \: \: \: \: x = - 11$

Step-by-step explanation:

${x}^{2} + 9x - 22 = 0 \\ {x}^{2} + 11x - 2x - 22 = 0 \\ x(x + 11) - 2(x + 11) = 0 \\ (x - 2)(x + 11) = 0 \\ x - 2 = 0 \: \: \: \: \: or \: \: \: \: \: x + 11 = 0 \\ x = 2 \: \: \: \: \: or \: \: \: \: \: x = - 11$
