Answer:
-54
Explanation:
First we need to use the distributive property on 7(x+5), so do 7×x + 7×5. Simplify that and you get 7x+35.
Subtract 35 from both sides and you get 7x= -63. Divide both sides by 7 and you get x= -9.
Now we can substitute -9 for x, so do 6×-9 and you get -54.
Hope this helps :)
Answer:
-94
Step-by-step explanation:
I am gonna use substitution method.
Solve for y in first equation,
y + 4x = 8
y = 8 -4x
Put the above y value in second equation,
5x + 2y = 13
5x + 2(8-4x) = 13
5x + 16 - 8x = 13
-3x = 13-16
-3x = -3
x = -3/-3
x = 1/1 = 1
Put the x value in first equation,
y + 4x = 8
y + 4(1) = 8
y = 8 - 4
y = 4
Hence, the solution is (1,4)
