-8(8+9g)=7(-2-11g)   First we distribute - one side at a times
-64-72g=-14-77g      Then we combine like terms -
                                 Add 64 to the right side of the equation
-72g=50-77g            Add 77g to the left side of the equation
5g=50                      Divide 5 by 50
g=10

diamong [38]
96% is the answer 100%/x%=125/120
(100/x)*x=(125/120)*x       - we multiply both sides of the equation by x
100=1.04166666667*x       - we divide both sides of the equation by (1.04166666667) to get x
100/1.04166666667=x
96=x
x=96

3p + 2q = 14<br> 10p + 6q = 44<br> What is p and what is q
Airida [17]

Answer:

p = 2 ; q = 4

Step-by-step explanation:

Given tbe equation :

3p + 2q = 14 - - - (1)

10p + 6q = 44 - - -(2)

What is p and what is q

This is a simultaneous equation ; using elimination method :

Multiply (1) by 6 and (2) by 2

18p + 12q = 84 - - - - (3)

20p + 12q = 88 - - - (4)

Subtract (3) and (4)

-2p = - 4

p = 4/2

p = 2

Put p = 2 in (1)

3p + 2q = 14

3(2) + 2q = 14

6 + 2q = 14

2q = 14 - 6

2q = 8

q = 8/2

q = 4

p = 2 ; q = 4
