Your answer is here mate!!!
Y = -3/4x + 9 ...eq( 1 )
Y = -1/2x + 8 ...eq( 2 )
Subsituting eq( 1 ) in eq( 2) we get,
-3/4x + 9 = -1/2x + 8
-3/4x + 1/2x = 8 - 9
-3x + 2x/4 = - 1
- x = -1 * 4
x = 4
Thus, The value of x is 4
Therefore,
Subsituting the value of x in eq(2 )
Y = -1/2 * 4 + 8
Y = -2 + 8
Y = 6
Thus, The value of y is 6
Hence, The value of x and y is 4 and 6 .
Answer:
x = 4
y = 6
Step-by-step explanation:
Step 1: Substitute -3/4(x) + 9 for y in y = -1/2(x) + 8.
- [tex]-3/4(x) + 9 = -1/2(x) + 8[/tex]
- [tex]-3/4(x) + 9 +1/2(x) = -1/2(x) + 8 + 1/2(x)[/tex] (add 1/2(x) to both sides)
- [tex]-1/4(x) + 9 = 8[/tex]
- [tex]-1/4(x)+9 - 9 = 8-9[/tex] (subtract 9 from both sides)
- [tex]-1/4(x) = -1[/tex]
- [tex]-1/4(x) * -4 = -1 * -4[/tex] (multiply both sides by -4)
- [tex]x = 4[/tex]
Step 2: Substitute 4 for x in y = -1/2(x) + 8
- [tex]y = -1/2(4) + 8[/tex]
- [tex]y = -2 + 8[/tex]
- [tex]y = 6[/tex]
Therefore, x = 4 and y = 6.
