(2x-1)×4=8x-4
I hope it helps ;)
Step-by-step explanation:
(3x+6)= 48(Alternate angles)
3x=48-6
3x=42
x=14
2y+48=5y-9 (Sum of two opposite interior angles= exterior angle)
48+9=5y-2y
57=3y
y=19
You need to use the distributive property. So you take the -9 from outside the parentheses and multiply itself by the numbers inside.
