Answer:
a = −bx+7x−4 over x
Step-by-step explanation:
solve for a:
7+ax−5x=3+2x−bx
add 5x to both sides:
ax−5x+7+5x=−bx+2x+3+5x
ax+7=−bx+7x+3
add -7 to both sides:
ax+7+−7=−bx+7x+3+−7
−bx+7x−4
lastly divide both sides by x.
Answer:
C
Step-by-step explanation:
using
x × y = 
, then
2 × 4
= 
= 
= 
= 6
