Answer:
2x - 2y = - 10
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
- 2(x - y) - 10 = 0 ← distribute parenthesis on left side
- 2x + 2y - 10 = 0 ( add 10 to both sides )
- 2x + 2y = 10 ( multiply through by - 1 )
2x - 2y = - 10 ← in standard form
Answer:
It the 3rd one it's correct cuz i worked it out
Can i have a brainliest please!!:)
Step-by-step explanation:
solve your system by substitution.
c+3d=8;c=4d−6
Rewrite equations:
c=4d−6;c+3d=8
Step: Solve c=4d−6for c:
c=4d−6
Step: Substitute4d−6forcinc+3d=8:
c+3d=8
4d−6+3d=8
7d−6=8(Simplify both sides of the equation)
7d−6+6=8+6(Add 6 to both sides)
7d=14
7d
7
=
14
7
(Divide both sides by 7)
d=2
Step: Substitute2fordinc=4d−6:
c=4d−6
c=(4)(2)−6
c=2(Simplify both sides of the equation)
Answer:
c=2 and d=2
