6.5 x 10 to the 3rd power
remember the base must be less than 10 and greather or equal to 1
X + x + x + x - 20 is equivalent to 4x - 20 because you can add the like terms, or the x's.
Answer:
x = 2
y = -3
Step-by-step explanation:
2x + 2y = -2, then 2y = -2 - 2x
3x - 2y = 12, then 2y = 3x - 12
so:
-2 - 2x = 3x - 12
add 2x and 12 to each side of the equation:
5x = 10
divide both sides by 5:
x = 2
2y = 3(2) - 12
2y = -6
divide both sides by 2:
y = -3
