X-c/2 = d
Multiply by 2 on both sides. Leaves us with:
x-c = 2d
Add 2 to both sides. Leaves us with:
x = 2d + c
Unless you have values to substitute into the variables, this is your answer:
x = 2d + c
Answer:
144
Step-by-step explanation:
Answer:
2(2x+5)=8x-18
2x+5=4x-9
2x=14
x=7
MN=2*7+5=19
Step-by-step explanation:
Answer: -1
Step-by-step explanation:
(2x(x+1)+2x(x-3))/(4x(x-3)(x+1)) = 2x/((x-3)(x+1))
(2x-2)/(2) = 2x
x-1 = 2x
-1 = x

150 + (10 x 30) = 450 M
250 + (10 x 20) = 450 M
