(5x-10)°=1
and (3x+40)°=1 so
5x-10=3x+40
5x-3x=40+10
2x=50
x=25
Answer : 125
Step-by-step explanation:
Cube
Solve for volume
V=125cm³
Subtract the 2nd row from the 1st row
5x = 5
Solve for x in the equation above
x = 1
Substitute x = 1 into any of the two equations above
Let's pick the first equation; 4x + 3y = -5
4 * 1 + 3y = -5
Solve for y in the equation above
y = -3
Therefore,
<u>x = 1</u>
<u>y = -3</u>
