Supplementary angles measure 180°. Make an equation:
Subtract 28 to leave the variable in the parentheses alone:
Add the 2 x's together:
Your new equation is:
Divide both sides by 2 to leave the variable alone
The supplement measures 76°
How many times does 2 go into 7. find that out and you will know
Set each equal since both equal y
x+1=y=3x-2
x+1=3x-2
minus x both sides
1=2x-2
add 2 both sides
3=2x
divide by 2
3/2=x
sub back
y=x+1
y=3/2+1
y=3/2+2/2
y=5/2
the best aproximation is
x=3/2
y=5/2
or the point (3/2,5/2)
in decimal
(1.5,2.5)
Answer:
