Answer:
10x times 1000 y minus 4x
Answer:
a = 180 - b - c
Step-by-step explanation:
To solve for a variable, move all the terms to the other side except a. You move terms across an equal sign using inverses.
So subtract b and c to the other side.
First do 90-40 because together they make the right angle.
Then do 50=3x+2
48=3x
16=x
Since the two equations equal y, set them equal to each other.
x-1=-2x+5
From there, solve for x.
First get x on one side, by using the addition property of equality.
x-1=-2x+5
3x-1=5
Isolate x by adding 1.
3x=6
Lastly get x all by itself by dividing each side by 3.
x=2
You can now substitute your x-value, 2, into one of the equations (or both, if you wish; either one will result in the same answer.)
y=x-1
y=2-1
y=1
OR
y=-2x+5
y=-2(2)+5
y=-4+5
y=1
Final answer:
x=2 and y=1
