Answer:
(-4,-2)
x=-4
y=-2
Step-by-step explanation:
-3x-4y=20
3(x-10y=16)=3x-30y=48
The reason I multiplied 3 to the second equation is for when we add the equations together the x will cancel out.
-3x-4y=20
+ <u>3x-30y=48</u>
-34y=68
Divide -34 from both sides.
y=-2
To find x you need to plug in -2 for y into one of the equations.
x-10y=16
x-10(-2)=16
Remember a negative times a negative equals a positive.
x+20=16
Subtract 20 from both sides.
x=-4
Hope this helps!
If not, I am sorry.
Answer:
Step-by-step explanation:
To solve this problem, isolate by the g on one side of the equation.
<h3><u>SOLUTIONS:</u></h3>
First, divide by -2 from both sides.
-2(4g-3)/-2=30/-2
Solve.
30/-2=-15
4g-3=-15
Next, add 3 from both sides.
4g-3+3=-15+3
Solve.
-15+3=-12
4g=-12
Then, divide by 4 from both sides.
4g/4=-12/4
Solve.
-12/4=-3
g=-3
Therefore, the correct answer is g=-3.
The answer would be D) :)
