Answer:
(3,6)
Step-by-step explanation:
Collect like terms
y -5x = -9
y + 2x = 12
Using elimination method
Subtract equation 2 from equation 1
y - 5x = -9
y + 2x = 12
---------------
0. -7x = -21
Divide both sides by -7
-7x = -21
---- -----
-7 -7
x = 3
Substitute x=3 into equation 1
y = 5(3) - 9
y = 15 - 9
y = 6
Solution is (x,y) = (3,6)
Answer:
x = - 
Step-by-step explanation:
Given
(x - 4) - (x + 7 ) = 8x
Distribute parenthesis noting second is distributed by - 1
x - 4 - x - 7 = 8x ← simplify left side
- 11 = 8x ( divide both sides by 8 )
x = -
73 is the answer I Hope dis help you
On 3 you subract 36-3 on 4 make the fraction a decimal by dividing the numerator by the denominator and then subtract 12 by the decimal you get and I'm pretty sure you should get both your answers.
