Answer:
answer is image
Step-by-step explanation:
You can plug -x - 1 for y in the first equation
2x - (-x - 1) = 10
2x + x + 1 = 10
Combine
3x = 9
Divide
x = 3
Plug 3 for x in any equation ( I'll use th second equation )
y = - (3) - 1
y = - 3 - 1 = -4
x = 3 ; y = -4
(3, -4)
Answer:
the y intercept is 4.
Step-by-step explanation:
Answer:
17x+4
Step-by-step explanation:
4(5x+1)-3x
20x+4-3x
17x+4
The constant is 15, divide 45 by 3 then you’ll get 15. multiply 15 with the minutes and you’ll get the sit-ups
