Answer:
X = -3
Y = -5
Step-by-step explanation:
2X - 3Y = 9
<u>- (-5X - 3Y) = 30</u>
7X + 0Y = -21
X = -3
2(-3) - 3Y = 9
- 3Y = 15
Y = -5
Answer:
a = 
- b
Step-by-step explanation:
Given
c(a + b) - d = f ( add d to both sides )
c(a + b) = f + d ( divide both sides by the multiplier c )
a + b = ( subtract b from both sides )
a = - b
Because 19 is being divided, you have to do the opposite. What's the opposite of division? Multiplication. So multiply 19 to -7, then get rid of the 19 on the x's side(cuz it was cancelled out). Now you should have x<-133. In case you don't know, positive times negative equals negative, but negative times negative equals positive.
