Answer:
x = 4.25
Step-by-step explanation:
The given equation of line is :
4(2x-5)+6=-3(-4x+8)-7
Solving LHS,
4(2x-5)+6 = 8x-20+6
= 8x-14
Solving RHS,
-3(-4x+8)-7 = 12x-24-7
= 12x-31
So,
8x-14 = 12x-31
Taking like terms together,
8x-12x = -31+14
-4x = -17
x = 4.25
So, the value of x is equal to 4.25.
Answer:
The correct one is A
Step-by-step explanation:
2x-y=10
y=1/2 × x+5
Now you substitute the value of y into the first equation.
2x - (1/2 × x+5) = 10
Solving this equation for x you get that x=6
Now substitute the value of x any of these two equations, doesn't matter. Let's say we do with the first one.
2×6-y=10
12-y=10
-y=10-12
-y= -2
y=2
And so you've got the first one which is, (x,y)=(6,2)
