Answer:
x=31/25
Step-by-step explanation:
3x+4/5=7-2x
Multiply through by 5
5(3x+4/5)=5(7-2x)
15x+4=35-10x
Collecting like terms
15x+10x=35-4
25x=31
x=31/25
Answer:
2 & 20
Step-by-step explanation:
100 x 2= 200
20 x 10= 200
It is y = 3x + 2, which means the y-intercept is 2. :)
long way
12 x 11 x 10 x 9 x 8 x 7 x6 x5 x4 x3x2/ 10x9x8x7x6x5x4x3x2x
but you can shorten that by crossing out identical numbers so you get 12 x 11
12 x 11 = 132 combinations
-2x*(-3x)-2x*(-4y)-2x*(-8)
answer :6x^2+8xy+16x
