18 but just add and if there is for the 8/8 that us ur answer hope i heloed
Answer:
3x + 2y = 315 -----(1)
2x + 4y = 450 -----(2)
from (1) 3x + 2y = 315
2y = 315-3x
y = 157.5 - 3/2x ---- (3)
substitute (3) into (2)
2x + 4y = 450
2x + 4(157.5 - 3/2x ) = 450
2x + 630 - 6x = 450
-4x = -180
x = 45 ---- (4)
substitute (4) into (3)
y = 157.5 - 3/2x
y = 157.5 - 3/2(45)
y = 90

Answer:
-1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x=6x+1
Step 2: Subtract 6x from both sides.
5x−6x=6x+1−6x
−x=1
Step 3: Divide both sides by -1.
−x
/-1=1/-1
x=-1
