Cant solve this please help me
9x-2y=8
Y=2x+1
2 answers:
9x=8+2y
x=8+2y/9
x2(4+y)/9
y-1=2x
y-1/2=x
x=y-1/2
the / is represented as a fraction. hoped this helped and if did plz mark as brainliest
Substitute 2x+1 where y is in the equation:
9x-2(2x+1)=8
Then distribute the -2(2x+1)
9x-4x+2=8
Then combine like terms (the x)
5x+2=8
Then do -2 on both side of the equation sign
5x+2=8
- 2 -2
Then you'd get
5x=6
Then divide 5 on both sides
X= 1.2
