Hi Brainiac
y=2x-3
y= 2x+5
Ok we need to solve y=2x-3 for y
Now substitute 2x-3 for y in y=2x+5
y=2x+5
2x-3=2x+5
Add -2x
2x-3-2x=2x+5-2x
-3=5
Add 3
-3+3=5+3
0=8

Answer:
where are the choices
Step-by-step explanation:
Answer:
cubes are 3-d while squares are 2-d so in order to solve them you need different equations.
Answer:
(- 5, 1 )
Step-by-step explanation:
- 6x - 14y = 16 → (1)
- 2x + 7y = 17 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate the x- term
6x - 21y = - 51 → (3)
Add (1) and (3) term by term to eliminate x
0 - 35y = - 35
- 35y = - 35 ( divide both sides by - 35 )
y = 1
Substitute y = 1 into either of the 2 equations and solve for x
Substituting into (1)
- 6x - 14(1) = 16
- 6x - 14 = 16 ( add 14 to both sides )
- 6x = 30 ( divide both sides by - 6 )
x = - 5
solution is (- 5, 1 )
