Because you can't solve for two variables at once, you can guess and trial/error.
You can also give x or y any value, and then solve for the opposite variable.

x = 0
y = -36
for example. There are more solutions.

   y + 8 = -4(x+7)
-36 + 8 = -4(0+7)
      -28 = 0 - 28
      -28 = -28

Step-by-step explanation:

a) Data and Calculations:

Hewlett-Packard (HPQ)    ExxonMobil (XOM)          Chevron CTX)

HPQ 6K10.63 ∨0.23          XOM 3K81.72 ∧ 0.08    CVX 9K84.45 ∨0.22

b) The total value of all the HP shares sold is 6,000 * $10.63

= $63,780

c) Joan's investment:

Investment = $63,780

Broker's commission = 1% = $637.80

Total cost of Joan's investment = $64,417.80 ($63,780 + $637.80)

d) Regne Broker's Commission:

Investment = $245,160 (3,000 * $81.72)

Commission = $3,677.40 ($245,160 * 1.5%)

e) Lisa received from Chevron's stock sale:

Investment = 9,000 * $84.45 = $760,050

Broker's fee = $28

Lisa's receipt = $760,022 ($760,050 - $28)
