Solve for x. i'm confused on whether we are suppose to expand or condense it, and on what log property do we use.
Answers: 2
![\bf log_4(x-2)+log_4(5)=log_4(70)\\\\ -----------------------------\\\\ log_{{ a}}(xy)\implies log_{{ a}}(x)+log_{{ a}}(y)\\\\ -----------------------------\\\\ log_4[5(x-2)]=log_4(70)\impliedby \textit{take out the } log_4 \textit{ from both sides} \\\\\\ 5(x-2)=70\implies x-2=\cfrac{70}{5}\implies x-2=14\implies x=16](/tpl/images/0429/7074/08cb3.png)

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
