Charlize and Camille solved the equation 4x – 2y = 8 for y. Their work is shown

Aloiza [94]

Answer:

The answer to your question is below

Step-by-step explanation:

Equation 4x - 2y = 8 solve for y

First, pass 4x to the right side -2y = -4x + 8

Pass -2 to the right side y = -4/-2 x + 8 /-2

Simplify y = 2x -4 or y = -4 + 2x

I can not see clearly the work of Charlize and Camille, but the one that has the answer shown above is correct.

A textbook store sold a combined total of 319 chemistry and history textbooks in a week. The number of history textbooks sold wa

beks73 [17]

H = history textbooks
c = chemistry textbooks

For this you'll have to do a system of equations:
$\left \{ {{h + c=319} \atop {h=c-89}} \right. \\ (c-89) + c = 319 \\ 2c - 89 = 319 \\ 2c - 89 +89 = 319 + 89 \\ 2c = 408 \\ 2c/2 = 408/2 \\ c = 204 \\ \\ h = c-89 \\ h=204-89 \\ h=115$

115 history textbooks and 204 chemistry textbooks were sold.
Hope this helps!
